title: Germatranyl substituted organotin (IV) carboxylates: synthesis spectroscopic characterization and biological activities.
abstract: Eight new organotin (IV) derivatives of general formula [N(CH2CH2O)3GeCH(R1)CH2COO](4-n)SnR(2)n, where n= 2, R(2) = C2H5 (1-5); R(1) = CH3 (1); C6H5 (2); p-CH3C6H4 (3); p-FC6H4(4); p-CH3OC6H4 (5) and n = 3, R(2) = CH2C6H5 (6-8), R(1) = CH3 (6); C6H5 (7); p-CH3C6H4 (8) have been synthesized by the reaction of di- or tri-organotin chloride with the corresponding germatranyl (substituted) propionic acid in the appropriate mole ratios using triethylamine as a base. The synthesized compounds were characterized by various spectroscopic techniques such as IR, multi-nuclear (1H, 13C, 119Sn) NMR, 119mSn Mössbauer, along with elemental analyses. They were also screened for in vitro anti-leishmanial activity against promastigotes of leishmania donovani and found some encouraging results.
