The crystal structure described by Pu2W2C3 crystallizes in the monoclinic C2/m space group. Pu(1) is bonded in a distorted pentagonal planar geometry to two equivalent C(1) and three equivalent C(2) atoms. W(1) is bonded to one C(1) and three equivalent C(2) atoms to form a mixture of distorted corner and edge-sharing WC4 trigonal pyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded to four equivalent Pu(1) and two equivalent W(1) atoms to form CPu4W2 octahedra that share corners with twelve equivalent C(2)Pu3W3 octahedra, edges with two equivalent C(1)Pu4W2 octahedra, and faces with two equivalent C(2)Pu3W3 octahedra. The corner-sharing octahedral tilt angles range from 39-58°. In the second C site, C(2) is bonded to three equivalent Pu(1) and three equivalent W(1) atoms to form CPu3W3 octahedra that share corners with six equivalent C(1)Pu4W2 octahedra, edges with six equivalent C(2)Pu3W3 octahedra, and  a faceface with one C(1)Pu4W2 octahedra. The corner-sharing octahedral tilt angles range from 39-58°. is represented by the CIF file [CIF]
