Abstract
Abstract
Well-shaped needles of the metal-rich phosphide Ce2Ru12P7 were grown in a lead flux, while a polycrystalline sample became available through a ceramic route followed by arc-melting. Ce2Ru12P7 crystallizes with the hexagonal Zr2Fe12P7 type: P6̅, a = 940.7(2), c = 389.8(1) pm, wR2 = 0.0342, 1001 F
2 values and 45 variables. Striking structural motifs in the Ce2Ru12P7 structure are tri-capped trigonal prisms that are centered by the phosphorus atoms: P1@Ru7Ce2, P2@Ru7Ce2 and P3@Ru9. Adjacent prisms are condensed via common edges to propeller-like building units.
