CsCrO3Cl crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded to three equivalent O(1), six equivalent O(2), and three equivalent Cl(1) atoms to form distorted CsCl3O9 cuboctahedra that share corners with two equivalent Cr(1)ClO3 tetrahedra, edges with six equivalent Cs(1)Cl3O9 cuboctahedra, edges with five equivalent Cr(1)ClO3 tetrahedra, and faces with four equivalent Cs(1)Cl3O9 cuboctahedra. Cr(1) is bonded to one O(1), two equivalent O(2), and one Cl(1) atom to form CrClO3 tetrahedra that share corners with two equivalent Cs(1)Cl3O9 cuboctahedra and edges with five equivalent Cs(1)Cl3O9 cuboctahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent Cs(1) and one Cr(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one Cr(1) atom. Cl(1) is bonded in a single-bond geometry to three equivalent Cs(1) and one Cr(1) atom.
