The crystal structure of EuRu4P12 is isotypic with filled skutterudite structures of rare earth transition metal poly-phosphides: RFe4P12 (R = Ce, Pr, Nd, Sm and Eu), RRu4P 12 (R = La, Ce, Pr and Nd) and ROs4P12 (R = La, Ce, Pr and Nd). The Ru cation is coordinated by six P anions in a distorted octa-hedral manner. The partially occupied Eu position (site occupancy 0.97) is enclosed by a cage formed by the corner-shared framework of the eight RuP 6 octa-hedra.
