Organotin complexes of succinyl bis-N-<em>p</em>-tolylhydroxamic acid and its analogues

Abstract

A few organotin complexes of the types R₂SnL and RSnClL with some newly synthesized ligands, viz., succinyl bi-N-<em>p</em>-tolylhydroxamic acid (L), glutaryl bis-N-<em>p</em>-tolyhydroxamic acid (L) and adipyl bis<em>-</em>N<em>-p-</em>tolylhydroxamic acid (L") have been prepare and characterize on the basis of elemental analyses, IR and NMR (^lH, ¹³C and ¹¹⁹Sn) spectral data. With glutaryl and adipylhydroxamic acids, the dimethyl tin derivative has been isolated possibly due to steric reasons. It is observed that except in the derivative (CY₃Sn)₂GPHA, the ligands are tetradentate in nature. The ¹¹⁹Sn NMR data suggest the hexa-coordinated nature of tin at R₂SnL type of compounds.
