Structure of tin(IV) complexes of 2-(2-selenidophenyl)imino-methylphenols formed by electrochemical cleavage of a diselenide bond

Abstract

The anodic oxidation of tin in an acetonitrile solution of the Schiff bases derived from bis(2-aminophenyl) diselenide and an appropriate salicylaldehyde yields tin(IV) compounds. The crystal structure of one, bis[2-(2-selenidophenyl)iminomethylphenoxo]tin(IV), was determined. The tin atom has octahedral co-ordination geometry with facial ligand occupancy. The Sn–N, Sn–O and Sn–Se bond lengths are 2.23(1), 2.04(1) and 2.558(2)Å respectively.
