- Abstract
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 119Sn Mössbauer, 1H, 13C, 119Sn NMR and IR spectroscopic techniques. 119Sn Mössbauer 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 119Sn-NMR chemical shifts confirm that the Sn atom in triorganotin complexes is four-coordinate in CDCl3 solution.
