The material structure described by Co3W3C crystallizes in the cubic Fd-3m space group. W(1) is bonded in a 8-coordinate geometry to two equivalent Co(1), four equivalent Co(2), and two equivalent C(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to six equivalent W(1) and six equivalent Co(2) atoms to form CoCo6W6 cuboctahedra that share edges with six equivalent C(1)W6 octahedra and faces with six equivalent Co(1)Co6W6 cuboctahedra. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to six equivalent W(1), three equivalent Co(1), and three equivalent Co(2) atoms. C(1) is bonded to six equivalent W(1) atoms to form CW6 octahedra that share corners with six equivalent C(1)W6 octahedra and edges with six equivalent Co(1)Co6W6 cuboctahedra. The corner-sharing octahedral tilt angles are 48°. is represented by the CIF file [CIF]
