Complexes of N-thiophosphorylthioureas RNHC(S)NHP(S)(OiPr)2 (HL) (R = pyridin-2-yl, pyridin-3-yl, 6-amino-pyridin-2-yl) with copper(I): Crystal structures of Cu(PPh3)nL (n = 1, 2)

Reaction of the potassium salts of N-thiophosphorylated thioureas of common formula RNHC(S)NHP(S)(OiPr)2 [R = pyridin-2-yl (HLa), pyridin-3-yl (HLb), 6-amino-pyridin-2-yl (HLc)] with Cu(PPh3)3I in aqueous EtOH/CH2Cl2 leads to mononuclear [Cu(PPh3)2La,b–S,S′] (1, 2) and [Cu(PPh3)Lc–S,S′] (3) complexes. Using copper(I) iodide instead of Cu(PPh3)3I, polynuclear complexes [Cun(L–S,S′)n] (4–6) were obtained. The structures of these compounds were investigated by IR, 1H, 31P{1H} NMR spectroscopy, ES-MS and elemental analyses. The crystal structures of Cu(PPh3)2Lb (2) and Cu(PPh3)Lc (3) were determined by single-crystal X-ray diffraction.
