Abstract

Co3W is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. W is bonded to twelve Co atoms to form WCo12 cuboctahedra that share corners with six equivalent WCo12 cuboctahedra, corners with twelve CoCo8W4 cuboctahedra, edges with eighteen CoCo8W4 cuboctahedra, faces with eight equivalent WCo12 cuboctahedra, and faces with twelve CoCo8W4 cuboctahedra. There are six shorter (2.55 Å) and six longer (2.56 Å) W–Co bond lengths. There are two inequivalent Co sites. In the first Co site, Co is bonded to four equivalent W and eight Co atoms to form distorted CoCo8W4 cuboctahedra that share corners with four equivalent WCo12 cuboctahedra, corners with fourteen CoCo8W4 cuboctahedra, edges with six equivalent WCo12 cuboctahedra, edges with twelve CoCo8W4 cuboctahedra, faces with four equivalent WCo12 cuboctahedra, and faces with sixteen CoCo8W4 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.48–2.63 Å. In the second Co site, Co is bonded to four equivalent W and eight equivalent Co atoms to form distorted CoCo8W4 cuboctahedra that share corners with four equivalent WCo12 cuboctahedra, corners with fourteen CoCo8W4 cuboctahedra, edges with six equivalent WCo12 cuboctahedra, edges with twelve equivalent CoCo8W4 cuboctahedra, faces with four equivalent WCo12 cuboctahedra,more »« less
