The crystal structure described by W4C3O is Tungsten Carbide-derived structured and crystallizes in the hexagonal P-6m2 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to three equivalent C(1) and three equivalent O(1) atoms to form distorted WC3O3 pentagonal pyramids that share corners with six equivalent W(1)C3O3 pentagonal pyramids, corners with six equivalent W(2)C6 pentagonal pyramids, edges with six equivalent W(1)C3O3 pentagonal pyramids,  a faceface with one W(1)C3O3 pentagonal pyramid, and  a faceface with one W(2)C6 pentagonal pyramid. In the second W site, W(2) is bonded to three equivalent C(1) and three equivalent C(2) atoms to form distorted WC6 pentagonal pyramids that share corners with six equivalent W(1)C3O3 pentagonal pyramids, corners with six equivalent W(2)C6 pentagonal pyramids, edges with six equivalent W(2)C6 pentagonal pyramids,  a faceface with one W(1)C3O3 pentagonal pyramid, and  a faceface with one W(2)C6 pentagonal pyramid. There are two inequivalent C sites. In the first C site, C(1) is bonded to three equivalent W(1) and three equivalent W(2) atoms to form distorted CW6 pentagonal pyramids that share corners with six equivalent C(2)W6 pentagonal pyramids, corners with six equivalent O(1)W6 pentagonal pyramids, edges with six equivalent C(1)W6 pentagonal pyramids,  a faceface with one C(2)W6 pentagonal pyramid, and  a faceface with one O(1)W6 pentagonal pyramid. In the second C site, C(2) is bonded to six equivalent W(2) atoms to form a mixture of distorted corner, edge, and face-sharing CW6 pentagonal pyramids. O(1) is bonded to six equivalent W(1) atoms to form distorted OW6 pentagonal pyramids that share corners with twelve equivalent C(1)W6 pentagonal pyramids, edges with six equivalent O(1)W6 pentagonal pyramids, and faces with two equivalent C(1)W6 pentagonal pyramids. is represented by the CIF file [CIF]
