Syntheses,Crystal Structure and Antibacterial Activities of Mononuclear and Tetranuclear Di-n-butyltin(IV) Complexes Constructed from 2-(4-formyl-2-methoxyphenoxy)Acetic Acid
Two new organotin(IV) carboxylates of composition n-Bu2Sn(O2CCH2OC6H3OCH3 CHO)2 (1) and {[n-Bu2Sn(O2CCH2 OC6H3OCH3CHO)2]2O}2 (2) were obtained by the reaction of n-Bu2SnO and 2-(4-formyl-2-methoxyphenoxy)acetic acid (LH). The compounds 1 and 2 have been characterised by elemental analysis and IR, 1H NMR and X-ray crystallographic diffraction studies. The tin atom in 1 is found to adopt the skew-trapezoidal bipyramidal geometry in the polymeric chains. The compound 2 adopts a dimeric ladder structure and contains a tetranuclear tin framework with six distannoxane rings. The antibacterial activities decrease in the order 2 > 1 > (n-Bu)2SnO > LH.
