Rb2PtSe2 crystallizes in the orthorhombic Immm space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1) and six equivalent Se(1) atoms. Pt(1) is bonded in a 4-coordinate geometry to four equivalent Rb(1) and four equivalent Se(1) atoms. Se(1) is bonded in a 8-coordinate geometry to six equivalent Rb(1) and two equivalent Pt(1) atoms.
Rb2PtSe2 crystallizes in the orthorhombic Immm space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1) and six equivalent Se(1) atoms. Both Rb(1)-Pt(1) bond lengths are 3.62 Å. There are two shorter (3.49 Å) and four longer (3.52 Å) Rb(1)-Se(1) bond lengths. Pt(1) is bonded in a 4-coordinate geometry to four equivalent Rb(1) and four equivalent Se(1) atoms. All Pt(1)-Se(1) bond lengths are 2.50 Å. Se(1) is bonded in a 8-coordinate geometry to six equivalent Rb(1) and two equivalent Pt(1) atoms.
