The crystal structure described by Tb2Cr2C3 crystallizes in the monoclinic C2/m space group. Tb(1) is bonded in a 5-coordinate geometry to two equivalent C(2) and three equivalent C(1) atoms. Cr(1) is bonded to one C(2) and three equivalent C(1) atoms to form a mixture of corner and edge-sharing CrC4 trigonal pyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to three equivalent Tb(1) and three equivalent Cr(1) atoms. In the second C site, C(2) is bonded to four equivalent Tb(1) and two equivalent Cr(1) atoms to form edge-sharing CTb4Cr2 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
