The compound described by CW3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to four equivalent W(1), four equivalent W(2), and four equivalent C(1) atoms to form distorted WW8C4 cuboctahedra that share corners with twelve equivalent W(1)W8C4 cuboctahedra, edges with eight equivalent W(1)W8C4 cuboctahedra, edges with eight equivalent C(1)W12 cuboctahedra, faces with four equivalent C(1)W12 cuboctahedra, and faces with ten equivalent W(1)W8C4 cuboctahedra. In the second W site, W(2) is bonded in a square co-planar geometry to eight equivalent W(1) and four equivalent C(1) atoms. C(1) is bonded to four equivalent W(2) and eight equivalent W(1) atoms to form distorted CW12 cuboctahedra that share corners with four equivalent C(1)W12 cuboctahedra, edges with eight equivalent C(1)W12 cuboctahedra, edges with sixteen equivalent W(1)W8C4 cuboctahedra, faces with four equivalent C(1)W12 cuboctahedra, and faces with eight equivalent W(1)W8C4 cuboctahedra. is represented by the CIF file [CIF]

The compound described by CW3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to four equivalent W(1), four equivalent W(2), and four equivalent C(1) atoms to form distorted WW8C4 cuboctahedra that share corners with twelve equivalent W(1)W8C4 cuboctahedra, edges with eight equivalent W(1)W8C4 cuboctahedra, edges with eight equivalent C(1)W12 cuboctahedra, faces with four equivalent C(1)W12 cuboctahedra, and faces with ten equivalent W(1)W8C4 cuboctahedra. In the second W site, W(2) is bonded in a square co-planar geometry to eight equivalent W(1) and four equivalent C(1) atoms. C(1) is bonded to four equivalent W(2) and eight equivalent W(1) atoms to form distorted CW12 cuboctahedra that share corners with four equivalent C(1)W12 cuboctahedra, edges with eight equivalent C(1)W12 cuboctahedra, edges with sixteen equivalent W(1)W8C4 cuboctahedra, faces with four equivalent C(1)W12 cuboctahedra, and faces with eight equivalent W(1)W8C4 cuboctahedra. is represented by the CIF file [CIF]
