摘　　要：Oxidation reaction of [Ru（PPh3）3Cl2] with tetraethylthiuram disulfide [Et2NCS2]2 or tetra-iso-propylthiuram disulfide [iPr2NCS2]2 afforded ruthenium（Ⅲ） complexes [Ru（PPh3）2（S2CNR2） Cl2]·CH2Cl2（R=Et 1,iPr 2） which were characterized by single-crystal X-ray diffraction.Complex 1 crystallizes in triclinic,space group P with a = 11.5065（6）,b = 12.1458（7）,c = 18.0034（9） ,α = 109.380（4）,β = 95.279（4）,γ = 97.969（4）°,V = 2324.8（2） 3 and Z = 2.Complex 2 belongs to the monoclinic system,space group P21/n with a = 12.5752（3）, b = 20.7562（5）, c = 17.6821（3） A, β =105.934（1）°, V = 4437.94（17） A^3 and Z = 4. Both mononuclear complexes 1 and 2 have an octahedral configuration around the central ruthenium atom which is bonded to one chelated dithiocarbamate ligand, two PPh3 ligands in mutually trans and two chlorides in mutually cis positions. The average Ru-S, Ru-P and Ru-C1 bond lengths are 2.377（2）, 2.412（2） and 2.369（2） A for 1, and 2.376（2）, 2.414（1） and 2.383（2） A for 2, respectively. The electrochemical properties of these two complexes were studied in CH2Cl2 solution by cyclic voltammetry.Oxidation reaction of [Ru（PPh3）3Cl2] with tetraethylthiuram disulfide [Et2NCS2]2 or tetra-iso-propylthiuram disulfide [iPr2NCS2]2 afforded ruthenium（Ⅲ） complexes [Ru（PPh3）2（S2CNR2） Cl2]·CH2Cl2（R=Et 1,iPr 2） which were characterized by single-crystal X-ray diffraction.Complex 1 crystallizes in triclinic,space group P with a = 11.5065（6）,b = 12.1458（7）,c = 18.0034（9） ,α = 109.380（4）,β = 95.279（4）,γ = 97.969（4）°,V = 2324.8（2） 3 and Z = 2.Complex 2 belongs to the monoclinic system,space group P21/n with a = 12.5752（3）, b = 20.7562（5）, c = 17.6821（3） A, β =105.934（1）°, V = 4437.94（17） A^3 and Z = 4.
