The first diorganotin(IV) complex 1 with N′-acylsalicylhydrazide has been successfully synthesized and structurally characterized by elemental analysis, FT-IR, NMR (1H, 13C and 119Sn) spectra and X-ray crystallography. The complex 1 is an infinite 1D polymer with tetranuclear organotin(IV) as secondary building units, which contains five- and seven-coordinated tin atoms.The first diorganotin(IV) complex 1 with N′-acylsalicylhydrazide has been successfully synthesized and structurally characterized by elemental analysis, FT-IR, NMR (1H, 119Sn) spectra and X-ray crystallography. The complex 1 is an infinite 1D polymer with tetranuclear organotin(IV) as secondary building units, which contains five- and seven-coordinated two kinds of tin atoms.

Triorganoantimony(V) complex (C5H5FeC5H4C(CH3)NO)2SbPh3 (1) has been prepared by the reaction of Ph3SbCl2 with acetylferroceneoxime C5H5FeC5H4C(CH3)NOH (2) in 1:2 molar ratio in anhydrous toluene. The complexes have been characterized by elemental analyses, IR and NMR (1H and 13C) spectroscopic studies, and biologic activity was measured. And crystal structures of 1, 2 were reported. The coordination geometry around the antimony atom in 1 was slightly distorted trigonal bipyramidal with the carbon atoms of the SbPh3 unit in equatorial positions and the two oxygen atoms of the oxime group occupying axial positions. The free oxime was clearly hydrogen bonded (H–N 2.10 Å/2.04 Å in 2) to essentially form a dimer.Triorganoantimony(V) complex (C5H5FeC5H4C(CH3)NO)2SbPh3 (1) has been prepared by the reaction of Ph3SbCl2 with acetylferroceneoxime C5H5FeC5H4C(CH3)NOH (2) in 1:2 molar ratio in anhydrous toluene.
