The structure described by DyWC2 crystallizes in the orthorhombic Pnma space group. Dy(1) is bonded to three equivalent C(2) and four equivalent C(1) atoms to form distorted DyC7 pentagonal bipyramids that share corners with four equivalent Dy(1)C7 pentagonal bipyramids, corners with three equivalent W(1)C5 trigonal bipyramids, edges with four equivalent Dy(1)C7 pentagonal bipyramids, edges with seven equivalent W(1)C5 trigonal bipyramids, and faces with two equivalent Dy(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 Dy(1)C7 pentagonal bipyramids, corners with four equivalent W(1)C5 trigonal bipyramids, edges with seven equivalent Dy(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 Dy(1) and two equivalent W(1) atoms to form CDy4W2 octahedra that share corners with four equivalent C(1)Dy4W2 octahedra, corners with nine equivalent C(2)Dy3W3 octahedra, edges with two equivalent C(1)Dy4W2 octahedra, edges with three equivalent C(2)Dy3W3 octahedra,  a faceface with one C(2)Dy3W3 octahedra, and faces with two equivalent C(1)Dy4W2 octahedra. The corner-sharing octahedral tilt angles range from 9-60°. In the second C site, C(2) is bonded to three equivalent Dy(1) and three equivalent W(1) atoms to form CDy3W3 octahedra that share corners with nine equivalent C(1)Dy4W2 octahedra, edges with three equivalent C(1)Dy4W2 octahedra, edges with six equivalent C(2)Dy3W3 octahedra, and  a faceface with one C(1)Dy4W2 octahedra. The corner-sharing octahedral tilt angles range from 9-60°. is represented by the CIF file [CIF]
