The structure described by GdWC2 crystallizes in the orthorhombic Pnma space group. Gd(1) is bonded in a 7-coordinate geometry to three equivalent C(2) and four equivalent C(1) atoms. W(1) is bonded to two equivalent C(1) and three equivalent C(2) atoms to form a mixture of corner and edge-sharing WC5 trigonal bipyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded to four equivalent Gd(1) and two equivalent W(1) atoms to form CGd4W2 octahedra that share corners with four equivalent C(1)Gd4W2 octahedra, corners with nine equivalent C(2)Gd3W3 octahedra, edges with two equivalent C(1)Gd4W2 octahedra, edges with three equivalent C(2)Gd3W3 octahedra,  a faceface with one C(2)Gd3W3 octahedra, and faces with two equivalent C(1)Gd4W2 octahedra. The corner-sharing octahedral tilt angles range from 8-61°. In the second C site, C(2) is bonded to three equivalent Gd(1) and three equivalent W(1) atoms to form CGd3W3 octahedra that share corners with nine equivalent C(1)Gd4W2 octahedra, edges with three equivalent C(1)Gd4W2 octahedra, edges with six equivalent C(2)Gd3W3 octahedra, and  a faceface with one C(1)Gd4W2 octahedra. The corner-sharing octahedral tilt angles range from 8-61°. is represented by the CIF card [CIF]
