The material described by HoWC2 crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded to three equivalent C(2) and four equivalent C(1) atoms to form distorted HoC7 pentagonal bipyramids that share corners with four equivalent Ho(1)C7 pentagonal bipyramids, corners with three equivalent W(1)C5 trigonal bipyramids, edges with four equivalent Ho(1)C7 pentagonal bipyramids, edges with seven equivalent W(1)C5 trigonal bipyramids, and faces with two equivalent Ho(1)C7 pentagonal bipyramids. W(1) is bonded to two equivalent C(1) and three equivalent C(2) atoms to form WC5 trigonal bipyramids that share corners with three equivalent Ho(1)C7 pentagonal bipyramids, corners with four equivalent W(1)C5 trigonal bipyramids, edges with seven equivalent Ho(1)C7 pentagonal bipyramids, and edges with two equivalent W(1)C5 trigonal bipyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded to four equivalent Ho(1) and two equivalent W(1) atoms to form CHo4W2 octahedra that share corners with four equivalent C(1)Ho4W2 octahedra, corners with nine equivalent C(2)Ho3W3 octahedra, edges with two equivalent C(1)Ho4W2 octahedra, edges with three equivalent C(2)Ho3W3 octahedra,  a faceface with one C(2)Ho3W3 octahedra, and faces with two equivalent C(1)Ho4W2 octahedra. The corner-sharing octahedral tilt angles range from 10-60°. In the second C site, C(2) is bonded to three equivalent Ho(1) and three equivalent W(1) atoms to form CHo3W3 octahedra that share corners with nine equivalent C(1)Ho4W2 octahedra, edges with three equivalent C(1)Ho4W2 octahedra, edges with six equivalent C(2)Ho3W3 octahedra, and  a faceface with one C(1)Ho4W2 octahedra. The corner-sharing octahedral tilt angles range from 10-60°. is represented by the CIF file [CIF]
