determined by X-ray crystallography. The spectral data of the complexes are consistent with sulfur coordination of the thiones to silver(I). The single crystal X-ray structure of complex 1, [Ag(PPh3)(thiourea)(NO3)]2·[Ag(PPh3)(thiourea)]2(NO3)2}, shows that the complex consists of two independent centrosymmetric binuclear units, each having the silver atoms coordinated to one PPh3 and two bridging thiourea
