摘要: A series of tri- and di-organotin(IV) derivatives the types R3SnL, R2SnL2 [(R2SnL)2O]2 have been synthesized by reaction chloride(s) with sodium cyclopropane carboxylate 3-cyclohexylpropanoate. Based on spectroscopic evidence (IR NMR), all triorganotin carboxylates were found to be penta-coordinated in solid state (except tricyclohexyltin derivative, which was four-coordinated) four-coordinated solution state. Attempted Me2SnCl2 1:2 stoichiometry afforded a bis(dicarboxylato tetraorganodistannoxane) complex, {[Me2Sn(cyclo-CH2)2CHCOO]2O}2. The X-ray diffraction this ‘dimethyltin(IV) complex’ shows that compound possesses tetranuclear aggregate one bridging bidentate other free organic ester type monodentate groups each Sn atom has five-coordinated geometry. These complexes also screened for their antifungal activities. Copyright © 2008 John Wiley & Sons, Ltd.
