Two zinc(II) coordination polymers {[Zn(tmtz)(H2O)4][Zn2(tmtz)2(sip)2]·3H2O}n (1) and [Zn3(tmtz)2(sip)2(H2O)4]·2H2O}n (2) (tmtz = 1,4-bis(1,2,4-triazol-1-ylmethyl)-2,3,4,5-tetramethylbenzene, sip = 5-sulfoisophthalate) were synthesized and structurally characterized. X-ray structural analysis shows that 1 is comprised of two distinct and crystallographically independent polymeric motifs polythreading together. The first motif of 1 is the (3,5)-connected 3D anionic network [Zn2(tmtz)2(sip)2]n2n− with point symbol of (42·6)(42·65·83). The second motif in 1 is the [Zn(tmtz)(H2O)4]n2n+ 1D cationic chain. A polythreading array was formed by a (3,5)-connected 3D anionic network and 1D cationic chains in 1. 2 exhibits a (3,4)-connected 2D network with point symbol of (42·8)(42·6·82·10) and constructs a 3D hydrogen bonding architecture. 1 and 2 are effective catalysts for the degradation of methyl orange in the presence of H2O2. The luminescence and thermal analyses are also performed.

Such a (3,4,4)-connected 3D network is unprecedented to the best of our knowledge. 7 displays a 2D (4,4) network which crystallizes in the chiral orthorhombic space group P212121. The results indicate that the central metal ions, polycarboxylate and flexible triazole co-ligands have a great effect on the formation and the structures of the coordination polymers. The thermal stability and luminescence were investigated. The crystal structures and solid-state circular dichroism (CD) spectra measurements confirmed the occurrence of the spontaneous resolution of 7 and demonstrated that the resulting crystal of 7 is a racemic mixture.

Abstract
Three hydrogen bond networks of cobalt(II) coordination polymers {[Co(btp)2(H2O)2]·2(1,2-Hbdc)·2H2O}n (1), {[Co(btp)(1,3-bdc)(H2O)]·1.5H2O}n (2) and {[Co(btp)2(H2O)2]·(1,4-bdc)}n (3) were synthesized by 1,3-bis(1,2,4-triazol-1-yl)propane (btp) and benzenedicarboxylate position isomers. Complex 1 is comprised of [Co(btp)2(H2O)]n2n+ 1D cation chains, 1,2-Hbdc− anions and lattice water molecules. The structure of 2 is an undulated 2D (4,4) network. Two adjacent networks interpenetrate each other to form a new 2D double-layers network which is sustained by the hydrogen bond interactions in 2. Complex 3 is comprised of [Co(btp)2(H2O)]n2n+ 1D cation chains and 1,4-bdc2− anions. These [Co(btp)2(H2O)]n2n+ 1D cations and 1,2-Hbdc−/1,4-bdc2− anions form 2D hydrogen bond networks in 1 and 3. The thermal stabilities of 1, 2 and 3 were investigated.

Seven cobalt(II) coordination polymers [Co(obtz)(Meip)]n (1), [Co(obtz)(ip)]n (2), {[Co2(obtz)2(tdc)2(H2O)]·2H2O}n (3), [Co(obtz)(1,4-bdc)(H2O)]n (4), [Co(obtz)(adc)]n (5), {[Co(obtz)2(fum)]·2H2O}n (6) and [Co(obtz)(hip)]n (7) (obtz = 1,2-bis(1,2,4-triazole-1-ylmethyl)benzene, Meip = 5-methylisophthalate, ip = isophthalate, tdc = 2.5-thiophenedicarboxylate, 1,4-bdc = 1,4-benzenedicarboxylate, adc = 1,3-adamantanedicarboxylate, fum = fumarate, hip = 5-hydroxyisophthalate) were synthesized. 1 shows a (3,4)-connected 2D network with the point symbol of (3·82)(32·4·82·9). 2 exhibits a (3,5)-connected 2D network with the point symbol of (42·6)(42·66·82). 3 presents a (3,6)-connected 2D network with the point symbol of (3·4·6)(32·44·54·63·7·8). 4 and 5 exhibit unusual 2D → 2D polycatenated network based on 2D sql network. 6 shows a 2D sql network. 7 presents the ladder-like 1D chain with side arms. The diverse structures demonstrate that the structures of coordination polymers can be tuned by the dicarboxylate and bis(triazole) co-ligands. The thermal stability of 1–7 was investigated. 1–7 are effective photocatalytic catalysts for the degradation of methyl orange.Seven cobalt(II) coordination polymers based on 1,2-bis(1,2,4-triazol-1-ylmethyl)benzene and dicarboxylate were synthesized and characterized which are effective photocatalytic catalysts for the degradation of methyl orange.

Three metal–organic frameworks (MOFs) {[Co4(OH)2(adc)6(H2O)5][Co2(OH)(btrb)]2·8H2O}n (1), {[Co4(OH)2(btrb)(nip)3(H2O)3]·4H2O}n (2·4H2O) and {[Co4(OH)2(btrb)(btc)2(H2O)2]·9H2O}n (3·9H2O) (btrb = 1,4-bis(1,2,4-triazol-4-ylmethyl)benzene, H2adc = 1,3-adamantanedicarboxylic acid, H2nip = 5-nitroisophthalic acid and H3btc = 1,3,5-benzenetricarboxylic acid) were synthesized by a hydrothermal method. 1 shows an unusual (3,4)-connected 2D network with a point symbol of (4·62)2(42·62·82) based on [Co4(μ3-OH)2] and [Co2(μ3-OH)] units. 2 is a 6-connected pcu topology based on the [Co4(μ3-OH)2] unit. 3 is a rare (3,8)-connected 3D framework with a rare point symbol of (4·5·6)2(42·56·616·72·82) based on the [Co4(μ3-OH)2] unit. The magnetic measurements reveal that 1–3 exhibit antiferromagnetic interactions between the adjacent cobalt(II) centers. 1–3 are good photocatalysts for the degradation of methylene blue (MB). The 1,2-position nitrogen atoms of the 4-substituted 1,2,4-triazole ligand act as strong σ-donators to form a quite stable coordination quadrangle with two metal ions. The btrb ligand containing two 4-substituted 1,2,4-triazole rings is favorable to form tetranuclear metal units. By the regulation of the multicarboxylate ligands, the connection number of [Co4(μ3-OH)2] clusters increases from 4 in 1 to 6 in 2 and then 8 in 3. This work presents a novel but effective method to design and regulate the connection number (4, 6 and 8 connected in this work) of MOFs with 4-substituted 1,2,4-triazole and rigid multicarboxylate ligands.

An unusual copper(II) coordination polymer {[Cu(tmtz)(H2O)4][Cu2(tmtz)2(sip)2]·4H2O}n (1) (tmtz = 1,4-bis(1,2,4-triazol-1-ylmethyl)-2,3,4,5-tetramethylbenzene, sip = 5-sulfoisophthalate) is synthesized by the hydrothermal reaction. X-Ray structural analysis shows that 1 is comprised of two distinct and crystallographically independent polymeric motifs polythreading together. The first motif of 1 is an unusual (3,5)-connected 3D anionic network [Cu2(tmtz)2(sip)2]. The second motif in 1 is the [Cu(tmtz)(H2O)4]n 1D cationic chain. A polythreading array formed by a (3,5)-connected 3D anionic network and 1D cationic chains. The catalytic performance exhibits that 1 is active as a catalyst for the degradation of methyl orange. The thermal analysis is also observed.
