Rb(PtGe)4 crystallizes in the tetragonal I4 space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Pt(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to two equivalent Rb(1) and five equivalent Ge(1) atoms. Ge(1) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms.
Rb(PtGe)4 crystallizes in the tetragonal I4 space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Pt(1) atoms. There are four shorter (3.39 Å) and four longer (3.50 Å) Rb(1)-Pt(1) bond lengths. Pt(1) is bonded in a 7-coordinate geometry to two equivalent Rb(1) and five equivalent Ge(1) atoms. There are a spread of Pt(1)-Ge(1) bond distances ranging from 2.48-2.61 Å. Ge(1) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms.
