Ca2Pd2Cd with W2B2Co-type Structure

  • Michael Johnscher and Rainer Pöttgen EMAIL logo


Ca2Pd2Cd was synthesized by high-frequency melting of the elements in a sealed niobium ampoule. Its structure was refined from single-crystal X-ray diffractometer data: W2B2Co type, Immm, a=444.58(6), b=590.25(6), c=863.07(10) pm, wR2=0.0252, 305 structure factors, 13 variables. The palladium and cadmium atoms build up twodimensional [Pd2Cd] networks which consist of Pd4Cd2 hexagons and Pd2Cd2 rectangles with 272.7 pm Pd-Pd and 273.2 pm Pd-Cd. The calcium atoms are coordinated by one Pd4Cd2 and one Pd2Cd2 unit. The structure of Ca2Pd2Cd is compared to that of Ce2Pd2Cd with its tetragonal Mo2B2Fe type.
