Synthesis and Crystal Structure of Novel Dimer of Bismuth (III) Complex with Dithiotetrahydropyrrolocarbamate:[Bi(S_2CNC_4H_8)_2(NO_3)]_2

摘要

A novel dimer of the bismuth (III) complex with dithiotetrahydropyrrolocarbamate,[Bi(S_2CNC_4H_8)_2centre not(NO_3)]_2,was synthesized and the crystal structure was determined by X-ray single crystal diffraction.The crystal belongs to a monoclinic system with space group P2_1,a=0.64718(13) nm,b=2.6738(6) nm,c=1.0423(2) nm,beta= 106.384(3)deg,Z=4,V= 1.730(3) nm~3,Dc=2.163 g/cm~3,mu=10.682 mm~(-1),F(000)=1072,R=0.0329,wR=0.0659.The structure shows a distorted pentagonal bipyramidal configuration with the seven-coordinated central Bi atom.In the crystal,the molecular packing in the unit cell reveals that the two adjacent molecules are symmetrically linked each other in the dimer by virtue of a couple of Bi-S interaction.
