Synthesis, characterization, in vitro antimicrobial and QSAR studies of diorganotin(IV) complexes of Schiff bases derived from 2-(3-methylbutanoyl)-1H-indene-1,3(2H)-dione and 4-substituted anilines

A series of some new diorganotin(IV) complexes [R2SnLCl] was synthesized by the reaction of 2-(3-methylbutanoyl)-1H-indene-1,3(2H)-dione and 4-substituted anilines (p-OCH3, p-NO2, p-CH3, p-Cl) with R2SnCl2, (R=Me, Et, n-Bu, Ph) in 1:1 molar ratio. The structure of the Schiff bases and their complexes were characterized by IR, 13C, 1H, 119Sn NMR, and mass spectral techniques. The synthesized ligands and derived organotin complexes were evaluated...
