RE4[P1-x(C2)x]3 (RE = La-Nd): The mixed anionic substructure formed by phosphorus and carbon

The rare-earth phosphide carbides RE4[P1-x(C 2)x]3 (RE = La, Ce, Pr, Nd) represent the first example of a mixed anionic substructure formed by phosphorus and carbon, being the first step toward the formation of the mixed inorganic P-C species. The peculiarities of the crystal structure, magnetic properties, XAS data, and quantum chemical calculation results confirm the ionic nature of the interaction beween the rare-earth cations RE and phosphorus anions, while complex interaction of π states of the C2 anions and d (and/or f) states of the RE components is indicated. Thus, despite the extensive chemical analogy between the phosphide carbides and phosphide suicides, the atomic interactions stabilizing the structural motif are slightly different.
