The crystal structure described by Ce3Cr is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to four equivalent Ce(1), four equivalent Ce(2), and four equivalent Cr(1) atoms to form distorted CeCe8Cr4 cuboctahedra that share corners with twelve equivalent Ce(1)Ce8Cr4 cuboctahedra, edges with eight equivalent Ce(1)Ce8Cr4 cuboctahedra, edges with eight equivalent Cr(1)Ce12 cuboctahedra, faces with four equivalent Cr(1)Ce12 cuboctahedra, and faces with ten equivalent Ce(1)Ce8Cr4 cuboctahedra. In the second Ce site, Ce(2) is bonded in a square co-planar geometry to eight equivalent Ce(1) and four equivalent Cr(1) atoms. Cr(1) is bonded to four equivalent Ce(2) and eight equivalent Ce(1) atoms to form CrCe12 cuboctahedra that share corners with four equivalent Cr(1)Ce12 cuboctahedra, edges with eight equivalent Cr(1)Ce12 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Cr4 cuboctahedra, faces with four equivalent Cr(1)Ce12 cuboctahedra, and faces with eight equivalent Ce(1)Ce8Cr4 cuboctahedra. is represented by the CIF card [CIF]
