The material structure described by Co3W is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. W(1) is bonded to twelve Co(1,1) atoms to form WCo12 cuboctahedra that share corners with six equivalent W(1)Co12 cuboctahedra; corners with twelve Co(1,1)Co8W4 cuboctahedra; edges with eighteen Co(1,1)Co8W4 cuboctahedra; faces with eight equivalent W(1)Co12 cuboctahedra; and faces with twelve Co(1,1)Co8W4 cuboctahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent W(1) and eight Co(1,1) atoms to form distorted CoCo8W4 cuboctahedra that share corners with four equivalent W(1)Co12 cuboctahedra; corners with fourteen Co(1,1)Co8W4 cuboctahedra; edges with six equivalent W(1)Co12 cuboctahedra; edges with twelve Co(1,1)Co8W4 cuboctahedra; faces with four equivalent W(1)Co12 cuboctahedra; and faces with sixteen Co(1,1)Co8W4 cuboctahedra. In the second Co site, Co(1) is bonded to four equivalent W(1) and eight Co(1,1) atoms to form distorted CoCo8W4 cuboctahedra that share corners with four equivalent W(1)Co12 cuboctahedra; corners with fourteen equivalent Co(1)Co8W4 cuboctahedra; edges with six equivalent W(1)Co12 cuboctahedra; edges with twelve Co(1,1)Co8W4 cuboctahedra; faces with four equivalent W(1)Co12 cuboctahedra; and faces with sixteen Co(1,1)Co8W4 cuboctahedra. is represented by the CIF card [CIF]
