Synthesis, spectroscopic and biological investigations of di-and triorganotin(IV) derivatives containing germanium: X-ray study of [Ph3GeCH(n-C3H7)CH2CO2]Sn[CH3]3

Abstract

Bimetallic di- and triorganotin(IV) germanium carboxylates were synthesized and characterized by elemental analyses, as well as IR, multinuclear NMR (1H, 13C, 119Sn) spectroscopy and tested for bioactivity. The structure of the representative compound, [Ph3GeCH(n-C3H7)CH2CO2]Sn[CH3]3 was determined by X-ray analysis and found to have a distorted trigonal bipyramidal geometry around the tin atom. Some selected compounds were also screened against different microbes and showed promising antibacterial and antifungal activity.
