The synthesis of a dimeric phosphine-stabilized phosphidogermanium(I)-amidogermanium(II) derivative is described. The reaction of amidinato phosphinoamidosilylene [L{(Ar)(Ph₂P)N}Si:] (1, L = PhC(NtBu)₂, Ar = 2,6-iPr₂C₆H₃) with GeCl₂·dioxane afforded a phosphine-stabilized phosphidogermanium(i) dimer moiety in a mixed-valent germanium(I,II) compound [:Ge(Cl){N(Ar)PPh₂}(Ph₂P)Ge:]₂ (3). The mechanism for the formation of 3 is also studied and reported.
