The structure described by Cs3In2Cl9 crystallizes in the trigonal R-3c space group. Cs(1) is bonded to four equivalent Cl(2) and eight equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with six equivalent Cs(1)Cl12 cuboctahedra, corners with four equivalent In(1)Cl6 octahedra, faces with eight equivalent Cs(1)Cl12 cuboctahedra, and faces with four equivalent In(1)Cl6 octahedra. The corner-sharing octahedral tilt angles range from 11-30°. In(1) is bonded to three equivalent Cl(1) and three equivalent Cl(2) atoms to form InCl6 octahedra that share corners with six equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, and  a faceface with one In(1)Cl6 octahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in a distorted L-shaped geometry to four equivalent Cs(1) and two equivalent In(1) atoms. In the second Cl site, Cl(1) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one In(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
