Three new complexes with phosphanylphosphido ligands, [Cu4{μ2-P(SiMe3)-PtBu}4](1), [Ag4{μ2-P(SiMe3)-PtBu2}4](2) and [Cu{η1-P(SiMe3)-PiPr2}2]–[Li(Diglyme)2] (3) were synthesized and structurally characterized by X-ray diffraction, NMR spectroscopy, and elemental analysis. Complexes 1 and 2 were obtained in the reactionsof lithium derivative of diphosphane tBu2P-P(SiMe3)Li·2.7THF withCuCl and [iBu3PAgCl]4, respectively. The X-ray diffraction analysis revealed that the complexes1 and 2 present macrocyclic, tetramericform with Cu4P4and Ag4P4core. Complex 3 was prepared in thereaction of CuCl with a different derivative of lithiated diphosphane iPr2P-P(SiMe3)Li·2(Diglyme). Surprisingly, the X-ray analysis of 3 revealed that in this reaction instead of the tetramer the monomericform, ionic complex [Cu{η1-P(SiMe3)-PiPr2}2]–[Li(Diglyme)2] was formed.
