The compound described by CrIn3 crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent In(1) atoms to form distorted CrIn6 cuboctahedra that share corners with six equivalent In(2)In12 cuboctahedra, edges with six equivalent Cr(1)In6 cuboctahedra, and edges with six equivalent In(2)In12 cuboctahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1) and three equivalent In(2) atoms. In the second In site, In(2) is bonded to six equivalent In(1) and six equivalent In(2) atoms to form distorted InIn12 cuboctahedra that share corners with six equivalent Cr(1)In6 cuboctahedra, corners with six equivalent In(2)In12 cuboctahedra, edges with six equivalent Cr(1)In6 cuboctahedra, edges with six equivalent In(2)In12 cuboctahedra, and faces with six equivalent In(2)In12 cuboctahedra. is represented by the CIF file [CIF]
