Cr3(W10C3)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 3-coordinate geometry to one Cr(1) and two equivalent C(1) atoms. In the second W site, W(2) is bonded to one Cr(2) and three equivalent C(1) atoms to form a mixture of edge and corner-sharing WCrC3 tetrahedra. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a cuboctahedral geometry to twelve equivalent W(1) atoms. In the second Cr site, Cr(2) is bonded in a distorted tetrahedral geometry to four equivalent W(2) atoms. C(1) is bonded in a 8-coordinate geometry to four equivalent W(1) and four equivalent W(2) atoms.
