RbFe2Te3 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Te(1) and six equivalent Te(2) atoms. Fe(1) is bonded in a 7-coordinate geometry to three equivalent Fe(1), two equivalent Te(1), and two equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1) and four equivalent Fe(1) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Fe(1) atoms.
RbFe2Te3 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Te(1) and six equivalent Te(2) atoms. Both Rb(1)-Te(1) bond lengths are 4.01 Å. There are four shorter (3.76 Å) and two longer (4.03 Å) Rb(1)-Te(2) bond lengths. Fe(1) is bonded in a 7-coordinate geometry to three equivalent Fe(1), two equivalent Te(1), and two equivalent Te(2) atoms. There is one shorter (2.54 Å) and two longer (2.81 Å) Fe(1)-Fe(1) bond lengths. Both Fe(1)-Te(1) bond lengths are 2.61 Å. Both Fe(1)-Te(2) bond lengths are 2.56 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1) and four equivalent Fe(1) atoms.
