A new three-dimensional (3-D) open-framework aluminophosphate (denoted AlPO-CJ31), with an Al/P ratio of 4/5, has been synthesized hydrothermally in the presence of diethylenetriamine (DETA) as the structure-directing agent (SDA). Its structure is determined by single-crystal X-ray diffraction and further characterized by X-ray powder diffraction, ICP, TG analyses and solid-state NMR techniques. The alternation of AlO4 tetrahedra, AlO5(H2O) octahedra and PO4 tetrahedra gives rise to an interrupted open-framework structure with parallel 8-membered ring (MR) and 12-membered ring channels along the [0 0 1] directions.

Using 1,3-propyldiamine (1,3-PDA) as the structure-directing agent, a new manganese (II)-substituted aluminophosphate [C3N2H12] · [MnAl3P4O17] · [H3O] (denoted MnAPO-14-PDA) containing five-coordinated Mn2+ ions has been hydrothermally synthesized. The structure has been solved by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction, ICP and TG analyses. Differently from our recently reported MnAPO-14-DABCO built up from MnO4(H2O)2 octohedra, AlO4 and PO4 tetrahedra, MnAPO-14-PDA is made of MnO5 trigonal bipyramid, AlO6 octohedra, AlO4 and PO4 tetrahedra. Its framework is analogous to aluminophosphate zeotype AFN in which 25% of the aluminum sites are replaced by Mn(II) atoms. The diprotonated 1,3-PDA cations and protonated H2O molecules reside in the 8-membered ring (MR) channels. Computational simulations indicate that the substitution sites and coordination modes of Mn atoms in the framework are determined by the structure-directing agent (SDA) through the host-guest interactions.

A new layered inorganic–organic hybrid aluminum phosphate-oxalate [H3N(CH2)4NH3]2[Al4(C2O4)(H2PO4)2(PO4)4]·4[H2O](AlPO-CJ25) has been synthesized hydrothermally, by using 1,4-diaminobutane (DAB) as structure-directing agent. The structure has been solved by single-crystal X-ray diffraction analysis and further characterized by IR, 31P MAS NMR, TG-DTA as well as compositional analyses.

The alternation of AlO4 tetrahedra and PO4 tetrahedra gives rise to the four-membered corner-sharing chains, which are interconnected through AlO6 octahedra to form the layered structure with 4,6-net sheet. Interestingly, oxalate ions are bis-bidentately bonded by participating in the coordination of AlO6, and bridging the adjacent AlO6 octahedra. The layers are held with each other through strong H-bondings between the terminal oxygens. The organic ammonium cations and water molecules are located in the large cavities between the interlayer regions.The alternation of AlO4 tetrahedra and PO4 tetrahedra gives rise to the four-membered corner-sharing chains, which are interconnected through AlO6 octahedra to form the layered structure with 4,6-net sheet.

Three-dimensional (3D) MAlP2O8·C2N2H9 open-frameworks have been successfully generated from 1D AlP2O83− chains using transition metal cations M2+ (M = Ni, Co and Fe). The 1D AlP2O83− chain compound whose chain structure is made up of corner-sharing Al2P2 four-membered rings is prepared solvothermally using ethylenediamine as a template; to the reactant mixture in which the one-dimensional AlP2O83− chain compound has already crystallized, transition metal cations are added. Structural analysis indicates that the terminal oxygen atoms attached to the one-dimensional AlP2O83− chains are exclusively coordinated to M2+ forming O–M–O bonds. XRD, DRS, ICP, CHN and Mössbauer techniques have been used to characterise the products. This work provides a new approach to the synthesis of 3D open-frameworks through the assembly of low-dimensional structures via transition metal cations.

The structure elucidation of a new zinc phosphate [Co^II(en)₃][Zn₄(H₂PO₄)₃(HPO₄)₂(PO₄)(2 H₂O)₂] (1) reveals that the racemic cobalt complex templates the zinc phosphate framework in such a way that the local C₂ point symmetry of the structural motif of the inorganic framework conforms with that of the cobalt complex pairing with it, in essence transferring its chirality to the inorganic host. An analysis of hydrogen bonding between the guest molecules and the inorganic host framework reveals that hydrogen bonding is responsible for the stereospecific structural arrangement. Upon examining previously reported chiral metal-complex-templated structures of metal phosphates, it is revealed that such hydrogen bonding is the common origin for inducing chirality transfer in metal–phosphate frameworks templated with chiral metal complexes.

A new layered aluminophosphate with an Al/P ratio of unity, designated AlPO-CJ9 (CJ9: China, Jilin University, number 9), has been synthesized hydrothermally. The crystalline product is characterized by powder and single-crystal X-ray diffraction (XRD), FT-IR and thermogravimetric analyses. The structure of AlPO-CJ9 contains [Al2P2O8(OH)2]2− macroanionic sheets stacked in an AAAA sequence. The inorganic layer based on a 3 × 4 × 6 net is featured by a type of chain built up by corner-sharing three-membered rings. The nonbonding interaction energies (Einter), including H-bonding, van der Waals and Coulombic interactions between the inorganic layer and several organic amines are studied, which are valuable in evaluating the templating abilities of the organic templates.

Employing piperazine as a template, a new three-dimensional aluminophosphate [Al11P12O48][C4H12N2][C4H11N2] (denoted AlPO-CJ11) has been prepared hydrothermally. The as-synthesized product has been characterized by X-ray powder diffraction, inductively coupled plasma, thermogravimetric and differential thermal analyses. Single crystal X-ray diffraction analysis shows that AlPO-CJ11 crystallizes in the trigonal space group Rc (no. 167) with a = 14.045(2) Å, c = 42.091(6) Å, V = 7191.0(16) Å3, and Z = 6. The framework structure of AlPO-CJ11 is constructed from two new types of chiral cage and has a new stoichiometry with an Al/P ratio of 11 ∶ 12. The possible locations of the templates in the cages have been investigated by molecular modeling.

This work presents our current progress on the rational design and synthesis of aluminophosphates with 2-D layer and 3-D open-framework structures. For the design of theoretical structures, we take two ways, one is using building block construction strategy to construct new 2-D networks and 3-D open frameworks. The other is using computer modeling method to systematically enumerate the theoretical network structures. The templating abilities of various amines in the formation of 2-D network or 3-D open-framework aluminophosphates can be evaluated in terms of non-bonding interaction energies of the guest templates and the host inorganic networks or frameworks. This well assists in the rational synthesis of target materials, with the good examples as 2-D Al3P4O163− anionic layers, and 3-D Al4P5O19(OH)2− open frameworks with structures analogous to AlPO–HDA (HDA: 1,6-hexanediamine). On the other hand, 3-D open framework can be rationally assembled by a lower-dimensional chain through incorporation of transition metal cations as illustrated by the successful synthesis of a 3-D open-framework nickel aluminophosphate [NiAlP2O8][C2N2H9].

A new microporous aluminophosphate [Al2P2O8][OCH2CH2NH3], denoted APO-CJ3 (CJ3: China, Jilin University, number 3), has been prepared from aqueous as well as non-aqueous systems. The as-synthesized product is characterized by scanning electron microscopy, X-ray powder diffraction, 27Al and 31P magic-angle-spinning NMR, thermogravimetric and differential thermal analyses. The structure has been solved by single-crystal X-ray diffraction analysis. APO-CJ3 crystallizes in the orthorhombic space group Pbca, with a=9.993(2) Å, b=8.583(3) Å, c=19.705(4) Å and Z=8. The structure resembles microporous aluminophosphate AlPO4-D, and is featured by chains of four-membered rings that are connected by UDUD linkages. The compound contains two kinds of Al atoms, one is four-coordinated and the other is six-coordinated linking another six-coordinated Al atom by the linkages of bridging O atom of ethanolamine template. Upon removal of the template above 450°C, the structure of APO-CJ3 transforms to AlPO4-D.

A model for biomembranes, the Langmuir monolayer formed from dipalmitoylphosphatidylcholine (DPPC) initiates the rapid nucleation of oriented KH2PO4 (KDP) crystals towards the (100) crystal face at the air/water interface. The oriented KDP crystals are nearly uniform in crystal size distribution, and their morphology changes from tetragonal prism into diamond lamellar. The crystals of oriented growth show a good second harmonic generation (SHG) signal.
