Rb2Be4Pt3 crystallizes in the orthorhombic Fmmm space group. Rb(1) is bonded in a 17-coordinate geometry to three equivalent Rb(1), eight equivalent Be(1), two equivalent Pt(2), and four equivalent Pt(1) atoms. Be(1) is bonded in a 3-coordinate geometry to four equivalent Rb(1), one Pt(2), and two equivalent Pt(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 4-coordinate geometry to four equivalent Rb(1) and four equivalent Be(1) atoms. In the second Pt site, Pt(1) is bonded in a 4-coordinate geometry to four equivalent Rb(1) and four equivalent Be(1) atoms.
Rb2Be4Pt3 crystallizes in the orthorhombic Fmmm space group. Rb(1) is bonded in a 17-coordinate geometry to three equivalent Rb(1), eight equivalent Be(1), two equivalent Pt(2), and four equivalent Pt(1) atoms. There is one shorter (3.90 Å) and two longer (4.15 Å) Rb(1)-Rb(1) bond lengths. There are a spread of Rb(1)-Be(1) bond distances ranging from 3.36-3.80 Å. Both Rb(1)-Pt(2) bond lengths are 3.82 Å. All Rb(1)-Pt(1) bond lengths are 3.60 Å. Be(1) is bonded in a 3-coordinate geometry to four equivalent Rb(1), one Pt(2), and two equivalent Pt(1) atoms. The Be(1)-Pt(2) bond length is 2.21 Å.
