【Abstract】 Bis(tricyclohexyltin) succinate, (c-C6H11)3SnO2CCH2CH2CO2Sn(C6H11-c)3 (1), has been synthesized by the reaction of tricyclohexyltin hydroxide and succinic acid in the benzene-ethanol and characterized by means of elemental analysis, IR, 1H NMR and X-ray single crystal diffraction. The crystal for 1 belongs to triclinic space group P-1 with a = 0.9891(9), b = 1.5402(8), c = 2.1316(15) nm, = 78.55(3), β = 82.39(3), = 83.71(4)°, Z = 3, V = 3.143(4) nm3, R1 = 0.0503, wR2 = 0.1361. The compound 1 is a di-nuclear tin coordination compounds in which tin atom possesses a distorted [SnC3O] tetrahedral geometry and a chain trimer supramolecular structure is formed by the weak intermolecular Sn…O interactions. Bioassay results show that 1 has good anti-bacterial activity against two bacteria, E. coli and S. aureus.更多还原
