Organotin (IV) complexes of aniline derivatives part-II,synthesis and spectroscopic characterization of organotin (IV) derivatives of 2- [(4-bromoanilino) carboxyl] benzoic acid

Abstract

A series of organotin(IV) complexes with the general formula $R_2SnL_2$ and $R_3SnL$, where R = $CH_3$, $C_2H_5$, n-$C_4H_9$, $C_6H_5$, $C_6H_5CH_2$ and L = 2-[(4-bromoanilino)carboxyl]benzoate, were synthesized and characterized by infrared, mass and multinuclear NMR (1H, 13C, 119Sn) spectroscopies. The coordination around tin in solid as well as in solution has been proposed on the basis of spectroscopic results.
