The compound described by WMoC2 is Tungsten Carbide-derived structured and crystallizes in the orthorhombic Pmm2 space group. W(1) is bonded in a 6-coordinate geometry to two equivalent C(1) and four equivalent C(2) atoms. Mo(1) is bonded to two equivalent C(2) and four equivalent C(1) atoms to form a mixture of distorted corner, edge, and face-sharing MoC6 pentagonal pyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded to two equivalent W(1) and four equivalent Mo(1) atoms to form distorted CMo4W2 pentagonal pyramids that share corners with four equivalent C(1)Mo4W2 pentagonal pyramids, corners with eight equivalent C(2)Mo2W4 pentagonal pyramids, edges with two equivalent C(1)Mo4W2 pentagonal pyramids, edges with four equivalent C(2)Mo2W4 pentagonal pyramids, and faces with two equivalent C(1)Mo4W2 pentagonal pyramids. In the second C site, C(2) is bonded to four equivalent W(1) and two equivalent Mo(1) atoms to form distorted CMo2W4 pentagonal pyramids that share corners with four equivalent C(2)Mo2W4 pentagonal pyramids, corners with eight equivalent C(1)Mo4W2 pentagonal pyramids, edges with two equivalent C(2)Mo2W4 pentagonal pyramids, edges with four equivalent C(1)Mo4W2 pentagonal pyramids, and faces with two equivalent C(2)Mo2W4 pentagonal pyramids. is represented by the CIF file [CIF]
