Copper(I) complexes of the general formula [Cu(PAr3)2(bztzdtH)X] (where X=Cl, Br, I; PAr3=tri-m-tolylphosphine, diphenyl-p-tolylphosphine; bztzdtH=benz-1,3-thiazolidine-2-thione) and [Cu(PAr3)(bztzdtH)X] (where X=Cl,Br; PAr3=tri-o-tolylphosphine) were prepared and characterized by eleme ntal analysis and their IR and UV-vis spectroscopic data. A single-crystal X-ray diffraction study was carried out on the complex [Cu(PPh3)2(bztzdtH)Cl]CH3COCH3. The complex exhibits a distorted tetrahedral CuSP2Cl core with Cu-P(1)=2.278(1) ?, Cu-P(2)=2.286(2) ? and Cu-Cl=2.377(1) ?, and bond angles around copper varying from 102.95(5)° for P(2)-Cu-Cl to 122.36(5)° for P(1)-Cu-P(2).
