摘要：

A series of organotin(IV) complexes of composition R3Sn[O2CC6H4{N=C(H) C6H3-2-OH(N=NC6H4R)}-p] (R = Ph or Bz; R = H, 2-CH3, 3-CH3, 4-CH3) have been investigated by Sn-119 Mossbauer, H-1, C-13, Sn-119 NMR and IR spectroscopic techniques. Sn-119 Mossbauer data indicated a distorted tetrahedral geometry for the triphenyltin(IV) complexes while the tribenzyltin complexes exhibit a distorted trigonal bipyramidal coordination geometry with equatorial benzyl groups and the axial positions occupied by an O atom from the carboxylate ligand and the O atom from the water ligand. The Sn-119-NMR chemical shifts confirm that the Sn atom in triorganotin complexes is four-coordinate in CDCl3 solution.
