Ce3Cr10N11 crystallizes in the cubic Fm-3m space group. Ce(1) is bonded in a 9-coordinate geometry to one N(3), four equivalent N(1), and four equivalent N(2) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. In the second Cr site, Cr(1) is bonded to one N(4) and three equivalent N(1) atoms to form a mixture of distorted edge and corner-sharing CrN4 tetrahedra. There are four inequivalent N sites. In the first N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ce(1), two equivalent Cr(1), and two equivalent Cr(2) atoms. In the second N site, N(2) is bonded to three equivalent Ce(1) and three equivalent Cr(2) atoms to form distorted NCe3Cr3 octahedra that share corners with six equivalent N(2)Ce3Cr3 octahedra, edges with three equivalent N(2)Ce3Cr3 octahedra, and  a faceface with one N(3)Ce6 octahedra. The corner-sharing octahedral tilt angles range from 20-32°. In the third N site, N(3) is bonded to six equivalent Ce(1) atoms to form face-sharing NCe6 octahedra. In the fourth N site, N(4) is bonded in a body-centered cubic geometry to eight equivalent Cr(1) atoms.
