The structure described by RbCrCl3 crystallizes in the monoclinic C2 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 9-coordinate geometry to one Cl(5), two equivalent Cl(1), three equivalent Cl(2), and three equivalent Cl(3) atoms. In the second Rb site, Rb(2) is bonded in a 9-coordinate geometry to one Cl(1), two equivalent Cl(5), three equivalent Cl(4), and three equivalent Cl(6) atoms. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form face-sharing CrCl6 octahedra. In the second Cr site, Cr(2) is bonded to one Cl(1), one Cl(2), one Cl(3), one Cl(4), one Cl(5), and one Cl(6) atom to form face-sharing CrCl6 octahedra. In the third Cr site, Cr(3) is bonded to two equivalent Cl(4), two equivalent Cl(5), and two equivalent Cl(6) atoms to form face-sharing CrCl6 octahedra. There are six inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 5-coordinate geometry to one Rb(2), two equivalent Rb(1), one Cr(1), and one Cr(2) atom. In the second Cl site, Cl(2) is bonded to three equivalent Rb(1), one Cr(1), and one Cr(2) atom to form a mixture of distorted face and corner-sharing ClRb3Cr2 square pyramids. In the third Cl site, Cl(3) is bonded in a 5-coordinate geometry to three equivalent Rb(1), one Cr(1), and one Cr(2) atom. In the fourth Cl site, Cl(4) is bonded to three equivalent Rb(2), one Cr(2), and one Cr(3) atom to form a mixture of distorted face and corner-sharing ClRb3Cr2 square pyramids. In the fifth Cl site, Cl(5) is bonded in a 5-coordinate geometry to one Rb(1), two equivalent Rb(2), one Cr(2), and one Cr(3) atom. In the sixth Cl site, Cl(6) is bonded in a 5-coordinate geometry to three equivalent Rb(2), one Cr(2), and one Cr(3) atom. is represented by the CIF file [CIF]
