Three tin ? complexes with N,N- dialkyl dithiocarbamates Ph3SnS2CN(CH3)C6 H5 (1),Ph3SnS2CN(C4H8NH) (2) and Sn(Cl)2(S2CNEt2)2 (3) have been synthesized. Th e crystal structures have been determined by X- ray sin- gle crystal diffraction. A crystal of the complex 1 is triclinic with space group , a=0.9485(3)nm, b=1.0491(3)nm, c=1.3631(4)nm, α =70.996(4)° , β =72.294(4)° , γ =79.609(4)° , Z=2, V=1.2168(6)nm3, Dc=1.453g· cm- 3, μ =1.234mm- 1, R =0.0442, wR=0.0858. A crystal of the complex 2 is monoclinic with space group P2 (1)/c, a=1.2214(2)nm, b=1.1651(2)nm, c=1.5769(3)nm,β =99.039(2)° , Z=2, V=2.21 62(7)nm3, Dc=1.532g· cm- 3, μ =1.352mm- 1, R=0.0267, wR=0.0591. A crystal of the complex 3 is triclinic with space group , a=0.7179(2)nm, b=0.9256(3)nm, c=1 .5327(5)nm,α =93.857(4)° ,β =98.992(4)° , γ =109.481(4)° , Z=2, V=0.9405(5 )nm3, Dc=1.717g· cm- 3, μ =2.076mm- 1, R=0.0263, wR=0.0662. In the complexes 1 and 2 the tin atoms rendered five- coordination in a distorted tigonal bipyr amidal structure and in the complex 3 the tin atom rendered six- coordination i n a distorted octahedron structure.

The novel bismuth?complex with dithiotetrahydropyrrolocarbamate, [Bi(S2CNC4H8 )3]2 has been synthesized. The crystal structure has been determined by X-ray s ingle crystal diffraction. The crystal belongs to monoclinic with space group C2 /c, a=1.6356(9) nm, b=1.1875(6) nm, c=2.3954(13) nm, β=100.741(8)°, Z=4, V=4.5 71(4) nm3, Dx=1.882g·cm-3,μ=8.267mm-1, F(000)=2512, R=0.0404, wR=0.0622. In this binuclear complex, each Bi?is seven coordinate with a distorted pentagonal bipyramidal geometry. CCDC: 179924.
