The structure described by UCr4C4 crystallizes in the tetragonal I4/m space group. U(1) is bonded in a body-centered cubic geometry to eight equivalent C(1) atoms. Cr(1) is bonded to four equivalent C(1) atoms to form a mixture of corner and edge-sharing CrC4 trigonal pyramids. C(1) is bonded to two equivalent U(1) and four equivalent Cr(1) atoms to form a mixture of distorted face, corner, and edge-sharing CU2Cr4 octahedra. The corner-sharing octahedral tilt angles range from 0-68°. is represented by the CIF file [CIF]
