Heteroleptic Cu(I) and Ag(I) complexes of N-thiophosphorylated tris-thioureas and triphenylphosphane

► Novel trifunctional N-thiophosphorylated thioureas are reported. ► The synthesis of their complexes with [M(PPh3)2]+ (M = Cu(I), Ag(I)) is also described. ► The compounds were examined by IR, NMR spectroscopy and ES mass spectrometry. ► Their luminescent properties were also studied.
