Synthesis and Molecular Structure of Binuclear Organotin Complex Bridged by Piperazinylbidithiocarbamate Anion

摘要

The title complex bistri(o-fluorbenzyl)tinpiperazinylbisdithiocarbamate (C48H44- F6N2S4Sn2, Mr = 1128.47) was synthesized by the reaction of tri(o-fluorbenzyl)tin chloride with piperazinylbisdithiocarbamate in 2:1 molar ratio. The structure was characterized by elemental analysis, IR and 1H NMR, and the crystal structure was determined by X-ray single-crystal diffrac- tion. The crystal belongs to triclinic, space group Pī with = 10.348(5), b = 10.636(6), c = 13.279(7) (A。),α = 68.445(9), β = 86.763(9), γ = 61.278(8)°, Z = 1, V = 1179(1) (A。)3, Dc = 1.589 g/cm3, μ = 1.296 mm-1, F(000) = 564, R = 0.0534 and wR = 0.0849. In the complex, the tin atoms are five-coordinate to a distorted tirgonal bipyramidal configuration.
