The structure described by Rb3FeS3 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 5-coordinate geometry to two equivalent S(1) and three equivalent S(2) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to one Fe(1), one S(2), and five equivalent S(1) atoms. Fe(1) is bonded to two equivalent Rb(2), two equivalent S(1), and two equivalent S(2) atoms to form edge-sharing FeRb2S4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 7-coordinate geometry to one Rb(1), five equivalent Rb(2), and one Fe(1) atom. In the second S site, S(2) is bonded in a 7-coordinate geometry to two equivalent Rb(2), three equivalent Rb(1), and two equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
