| Abstract: Three tin (Ⅳ) complexes with N,N-dialkyl dithiocarbamates Ph3SnS2CN(CH3)C6H5 (1),Ph3SnS2CN(C4H8NH) (2) and Sn(Cl)2(S2CNEt2)2 (3) have been synthesized. The crystal structures have been determined by X-ray sin- gle crystal diffraction. A crystal of the complex 1 is triclinic with space group P1, 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=2.2162(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 P1, 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 bipyramidal structure and in the complex 3 the tin atom rendered six-coordination in a distorted octahedron structure.
