Co3W is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. W(1) is bonded to twelve equivalent Co(1) atoms to form WCo12 cuboctahedra that share corners with twelve equivalent W(1)Co12 cuboctahedra, edges with twenty-four equivalent Co(1)Co8W4 cuboctahedra, faces with six equivalent W(1)Co12 cuboctahedra, and faces with twelve equivalent Co(1)Co8W4 cuboctahedra. Co(1) is bonded to four equivalent W(1) and eight equivalent Co(1) atoms to form distorted CoCo8W4 cuboctahedra that share corners with twelve equivalent Co(1)Co8W4 cuboctahedra, edges with eight equivalent W(1)Co12 cuboctahedra, edges with sixteen equivalent Co(1)Co8W4 cuboctahedra, faces with four equivalent W(1)Co12 cuboctahedra, and faces with fourteen equivalent Co(1)Co8W4 cuboctahedra.
