| 摘 要： | 1 INTRODUCTION Organotin esters of carboxylic acids are widely used as biocides, fungicides and homogeneous ca- talysts in industry1～3]. Recently, pharmaceutical pro- perties of organotin esters of carboxylic acids have been investigated for their antitumour activity4, 5]. Studies on organotin compounds containing car- boxylate ligands with additional donor atoms (e.g. N, O or S) that are available for coordination to the tin atom have revealed that new structural types may lead to di…

| Abstract: | A novel organotin complex Ph3Sn(C2H5OH)(OCOC5H3NBr)SnPh3(OCOC5H3NBr)] has been synthesized by the reaction of 5-bromonicotinic acid with triphenyltin hydroxide in ethanol and characterized by elemental analysis, IR and 1H NMR. The crystal structure was determined by X-ray single-crystal diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 15.564(2), b = 24.975(4), c = 12.2973(19) , β = 92.224(2)o, Z = 4, V = 4776.5(13) 3, Dc = 1.596 g/cm3, μ(MoKα) = 2.765 mm-1, F(000) = 2264, R = 0.0385 and wR = 0.0667. In the molecular structure of the title complex, the tin atoms are five-coordinated in a trigonal bipyramidal geometry. |
