Abstract: Two novel bismuth(III) complexes with dithiocarbamate [Bi(S2CNEt2)3]2 and [Bi(S2CNC4H8)2(NO3)].[1,10-Phen] (2) have been synthesized . The crystal structures have been determined by X-ray single crystal diffraction. The crystals of complex 1 belong to monoclinic with space group P21/c, a =12.625(2), b = 13.628(3), c = 14.835(3) Å, β= 100.002(2)o, Z =2,V = 2513.7 (8) Å3, Dc = 1.727 mg/m3, μ= 7.517 mm-l, F(000) = 1280, R =0.0306 and wR =0.0818. In this binuclear complex, the two Bi atoms are seven-coordinated, and each of the two atoms has distorted pentagonal bipyramidal geometry. Each of central Bi atoms is surrounded equatorially by five S atoms and axially by two S atoms. Two of the six bidentate ligands are bridged in such a way that each sulfur atom is simultaneously bonded to both Bi atoms. The crystals of complex 2 belong to triclinic with space group P-1, a = 10.10(3), b = 10.43(3), c = 13.52(3) Å, α=79.71(4), β=85 .67(4), γ=66.29(4)o, Z=2, V= 1284(5) Å3, Dc= 1.924 mg/m3, μ=7.227 mm-1 , F(000)=724, R=0.0656, wR=0.0997. In this complex, the bismuth atom is eight-coordinated in a capped distorted pentagonal bipyramidal geometry. Around the central Bi atom, three S atoms and two N atoms occupy equatorial positions and one S atom and one O atom occupy axial positions.
