【摘要】 CS2在Cu-S键中插入产物(Ph3P)2Cu(S2CSPh)与CH2Cl2-C2H5OH混合溶剂反应,获得单核铜配合物(Ph3P)2Cu(S2COOC2H5)和双核铜配合物(Ph3P)3Cu2Cl2等化合物晶体,用X-射线单晶衍射法测定前者的晶体结构。晶体的化学式为C39H35CuOP2S2,分子量为709.3,空间群P21/n,a=9.329(6),b=18.664(11),c=20,341(13),β=95.59(5)°,V=3525(4)3,Dc=1.337g/cm3,Z=4,F(000)=1492,μ=0.852mm-1,R=0.045。
【Abstract】 Mononuclear copper complexes with structure of (Ph3P)2Cu (S2CSR) formed by insertion of CS2 into Cu-S bonds can react with various solvents undergoing some nucleophilic reactions.The title compound was obtained from the reaction of starting material (Ph3P)2 Cu (S2CSPh)with CH2Cl2-C2H5OH mixed solvent and then self-assembly in the solution.The crystal belongs to the space group P21/n ,a= 9. 329(6),b= 18.664(11),c= 20.341 (13)A,β= 95. 59(5)°,V =3525(4) A 3.Dc =1. 337 g/cm ̄3.Z= 4. The final R is 0. 045 for 3150 independent reflecrions.The complex contains a dithiocarbonate ligand.
【Key words】 insertion of CS2; copper complex; crystal structure; dithiocarbonate; activated fragment; self-assembly;
