Materials Data on U(CrC)4 by Materials Project
UCr4C4 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. U4+ is bonded in a body-centered cubic geometry to eight equivalent C4- atoms. All U–C bond lengths are 2.52 Å. Cr3+ is bonded to four equivalent C4- atoms to form a mixture of corner and edge-sharing CrC4 trigonal pyramids. There is two shorter (1.95 Å) and two longer (1.96 Å) Cr–C bond length. C4- is bonded to two equivalent U4+ and four equivalent Cr3+ atoms to form a mixture of distorted corner, edge, and face-sharing CU2Cr4 octahedra. The corner-sharing octahedra tilt angles range from 0–69°.
