Abstract: Mononuclear copper complexes with structures of (Ph3P)2Cu(S2CSR), formed by insertion of CS2 into Cu-S bonds, can react with a various solvents undergoing some nucleophilic reactions. The two title compounds(IV, V)were obtained from the reaction of starting material(R=But, C6H2Pri3-2, 4, 6) with CH2I2-acetone mixed-solvent in the presence of pyridine and then self-assemblyin the same solution. Crystal data for compound IV: space group C2/c, a=26.112(6), b=14.499(3), c=11.357(2)Å, β=95.18(2)Å, V=4282(15)Å3, Dc=1.650g/cm3, Z=4, R=0.0334 for 2182 independent reflections. Crystal data for compound V: space group P21/n, a=11.389(4), b=11.698(5), c=13.227(7)Å, β=114.99(4)°, V=1597(13)Å3, Dc=2.563g/cm3, Z=4, R=0.0627 for 1891 independent reflection.

Key words: CS2 insertion reaction, dinuclear copper complex, crystal structure
