Reaction of the potassium salts of N-thiophosphorylated thioureas of common formula RC(S)NHP(S)(OiPr)2 [R=morpholin-N-yl (HLa), piperidin-N-yl (HLb), NH2(HLc), PhCH2NH(HLd)] with Cu(PPh3)3I in aqueous EtOH/CH2Cl2 leads to mononuclear [Cu(PPh3)2L–S,S ] complexes. Using copper(I) iodide instead of Cu(PPh3)3I, polynuclear complexes [Cun(L–S,S )n] were obtained. The structures of these compounds were investigated by ES-MS, elemental analyses, 1H and 31P NMR in solution, IR and 31P solid-state MAS NMR spectroscopy. The crystal structures of [Cu3L3a] and [Cu(PPh3)2Lb] were determined by single-crystal X-ray diffraction.
