摘要
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）°A, β = 92.224（2）°, Z = 4, V = 4776.5（13）°A^3, Dc = 1.596 g/cm^3, 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.
