Abstract: A novel dimer of the bismuth ( Ⅲ ) complex with dithiotetrahydropyrroloearbamate, [Bi(S2CNC4H8)2 ·(NO3)]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 P21/n, a=0.64718(13) nm, b=2.6738(6) nm, c=1.0423(2) nm, β=106.384(3)°, Z=4, V=1.730(3) nm3, Dc=2.163 g/cm3, μ=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.
