A series of neutral complexes, namely, [N-(2-hydroxy-4-nitrophenyl)-3- hydroxysalicylideneiminato]-diphenyltin(IV) (Ia), [N-(2-hydroxy-4-nitrophenyl)- 3-methoxysalicylideneiminato]diphenyltin(IV) (IIa) and [N-(2-hydroxy-4- nitrophenyl)-3-ethoxysalicylideneiminato]diphenyltin(IV) (IIIa) were prepared by the reaction of diphenyltin dichloride on the corresponding Schiff bases. The Schiff bases were the reaction products of 2-hydroxy-4-nitroaniline and appropriate salicylaldehydes. AU the compounds were characterized by elemental analysis, 1H-NMR, 13C-NMR, IR and mass spectroscopy. Compound IlIa was also characterized by single crystal X-ray diffraction and shows a C2NO2 coordination geometry nearly half-way between a trigonal bipyramidal and square pyramidal arrangement. In the solid state, π - π interactions exist between the aniline fragments of neighbouring molecules. Copyright © 2007 John Wiley & Sons, Ltd.
