  Abstract:   Salt metathesis reactions between K[{SP(OEt)2}(O2SC6H4Cl-4)N] and the copper(I) species CuCl and (Ph3P)2CuNO3, respectively, resulted in the new complexes [Cu({SP(OEt)2}(O2SC6H4Cl-4)N)] (1) and [Cu(PPh3)2({SP(OEt)2}(O2SC6H4Cl-4)N)] (2). The two compounds were characterized by multinuclear NMR (1H, 13C, 31P). Single-crystal X-ray diffraction studies revealed a monomeric structure with a bidentate, monometallic biconnective behavior of the organophosphorus(V) ligand in case of compound 2. For compound 1 the NMR spectra suggest intermolecular associations in solution.

Keywords: Organophosphorus ligands, copper(I) complexes, structure elucidation
