Synthesis and characterization of mixed ligand copper(I) complexes containing halides, triphenylarsine and N,N-dimethyl-N'-phenylthiourea (dmptH), N,N-dibutyl-N'-phenylthiourea (dbptH) or 1,3-thiazolidine-2-thione (tzdtH). The X-ray crystal structure of [Cu(PPh3)2(dmptH)Cl]

The arsine complexes [Cu(PPh3)2(LH)X] (LH=N,N-dimethyl-N'-phenylthiourea(dmptH), N,N-dibutyl-N'-phenylthiourea (dbptH) or 1,3-thiazolidine-2-th ione (tzdtH); X=Cl, Br, I) have been prepared and characterized on the basis of analytical, IR, electronic (UV-vis), (1)H NMR, conductivity and magnetic measurements. In all cases there is a distorted tetrahedral environment arround copper(I) and the ligands (LH) bind through thione sulphur atom to copper(I). We also report the crystal structure of complex [Cu(PPh3)2(dmptH)Cl] which shows that metal ion has a distorted tetrahedral geometry with bond lengths Cu-S=2.459(2), Cu-Cl=2.308(1), Cu-P(1)=2.305(1) and Cu-P(2)=2.313(1) ?. The NH is intramolecularly hydrogen bonded to Cl with a bond distance NH...Cl=2.31 ?.
