The structure described by Ni2W4C crystallizes in the cubic Fd-3m space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to four equivalent Ni(1) and two equivalent C(1) atoms. In the second W site, W(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. Ni(1) is bonded in a 12-coordinate geometry to three equivalent W(2), six equivalent W(1), and three equivalent Ni(1) atoms. C(1) is bonded to six equivalent W(1) atoms to form corner-sharing CW6 octahedra. The corner-sharing octahedral tilt angles are 41°. is represented by the Crystallographic Information File (CIF) [CIF]
