In contrast to d-metal polyphosphide (Pn) complexes the lanthanide (Ln) ones are far less common. Their story starts from [(Cp*2Sm)4P8] obtained by reduction of P4 with [Cp*2Sm] [1]. This “reductive approach” is found to be really useful for preparation of mixed d-metal/Ln Pn-complexes: the reactions of d-metal Pn-complexes with Ln(II) compounds lead to unusual transformations of Pn-ligands in the coordination sphere of metals and to formation of unprecedented mixed d-metal/Ln polyphosphides. Some examples are given in the Figure 1: the reactions (i)-(iii) illustrate different variants of dimerization of Pn units caused by transfer of electron from Sm(II), while the reaction (iv) exhibit a complicated “disproportionation” of {Mo2P2} moiety. The report collates results of our study focused on the reactivity of d-metal Pn-complexes towards reduction by Ln(II) compounds [2-6]. The discussion will be complemented with results of other authors and the data obtained for the heavier analogues of phosphorus [7].
