Complexes of N-thiophosphorylthiourea α-naphthylnhc(S)NHP(S)(OiPr)2 (HL) with copper(I). crystal structures of HL and Cu(PPh3)2L

Reaction of the potassium salt of N-thiophosphorylated thiourea α-naphthylNHC(S)NHP(S)(OiPr)2 (HL) with Cu(PPh3)3I in aqueous EtOH/CH2Cl2 leads to the mononuclear complex [Cu(PPh3)2L-S,S′]. By using copper(I) iodide instead of Cu(PPli3)3I, the polynuclear complex [Cun(L-S,S′)n was obtained. The structures of these compounds were investigated by elemental analysis, H and 31P{1H} NMR and IR spectroscopy. The crystal structures of HL and Cu(PPh3)2-L were determined by singlecrystal X-ray diffraction. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA
