摘要

Reaction of the potassium salt of the N-thiophosphorylated thiourea Et2NC(S)NHP(S)(OiPr)(2) (HL) with a mixture of AgNO3 and PPh3 in aqueous EtOH/CH2Cl2 leads to the mixed-ligand silver(I) complex [Ag (PPh3)(2){Et2NC(S)NP(S)(OiPr)(2))] ([Ag(PPh3)(2)L]). Recrystallization of [Ag(PPh3)(2)L] from an acetone/n-hexane mixture leads to the decomposition of the starting complex with the formation of [Ag(PPh3){Et2NC(S)NP(S) (OiPr)(2)}] [Ag(PPh3)L]), [Ag(PPh3)(3)NCS]center dot(CH3)(2)C=O and Et2NP(S)(OiPr)(2). The structures of [Ag(PPh3)(2)L], [Ag(PPh3)L], [Ag(PPh3)(3)NCS]center dot(CH3)(2)C=O and Et2NP(S)(OiPr)(2) were all investigated by IR. P-31{H-1} and H-1 NMR spectroscopy, and their compositions were established by elemental analysis. The crystal structure of the complex [Ag(PPh3)(3)NCS]center dot(CH3)(2)C=O obtained from single crystal X-ray diffraction is presented.
