Abstract
Abstract Two organotin complexes of 2-phenyl-1,2, 3-triazole-4-carboxylic acid, {[n-Bu2Sn(OOCC2HN3Ph-2)]2O}2 (1) and (c-C6H11)3Sn(OOCC2HN3Ph-2)(C2H5OH) (2), have been synthesized and characterized by means of elemental analysis, FT-IR, NMR (1H, 13C and 119Sn) spectra and X-ray single crystal diffraction. Compound 1 is a centrosymmetric tetranuclear bis(dicarboxylatotetra-n-butyldistannoxane) complex containing two distinct types of carboxylate moieties and tin atoms with [SnC2O3] trigonal-bipyramidal and [SnC2O4] skew-trapezoidal-bipyramidal geometries. Compound 2 possesses a [SnC3O2] trigonal bipyramidal environment with the axial positions occupied by the carboxylate oxygen and hydroxyl oxygen of an ethanol molecule and forms a one-dimensional supramolecular structure by intermolecular O-H···O hydrogen bonds. Bioassay results have shown that the two compounds possess good in vitro cytotoxic activity against three human tumor cell lines (HeLa, CoLo205 and MCF-7).
