RbPt5 crystallizes in the triclinic P1 space group. Rb(1) is bonded in a 3-coordinate geometry to one Pt(2), two equivalent Pt(1), and four equivalent Pt(5) atoms. The Rb(1)-Pt(2) bond length is 2.62 Å. There is one shorter (2.39 Å) and one longer (2.43 Å) Rb(1)-Pt(1) bond length. There are a spread of Rb(1)-Pt(5) bond distances ranging from 3.68-3.78 Å. There are five inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to two equivalent Rb(1) and one Pt(5) atom. The Pt(1)-Pt(5) bond length is 2.45 Å. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to one Rb(1), one Pt(4), and two equivalent Pt(3) atoms. The Pt(2)-Pt(4) bond length is 1.07 Å. There is one shorter (1.55 Å) and one longer (1.61 Å) Pt(2)-Pt(3) bond length. In the third Pt site, Pt(3) is bonded in a rectangular see-saw-like geometry to one Pt(5), two equivalent Pt(2), and two equivalent Pt(4) atoms. The Pt(3)-Pt(5) bond length is 2.88 Å. There is one shorter (1.55 Å) and one longer (1.61 Å) Pt(3)-Pt(4) bond length. In the fourth Pt site, Pt(4) is bonded in a distorted single-bond geometry to one Pt(2), two equivalent Pt(3), and two equivalent Pt(5) atoms. There is one shorter (2.76 Å) and one longer (2.80 Å) Pt(4)-Pt(5) bond length. In the fifth Pt site, Pt(5) is bonded in a 10-coordinate geometry to four equivalent Rb(1), one Pt(1), one Pt(3), two equivalent Pt(4), and two equivalent Pt(5) atoms. Both Pt(5)-Pt(5) bond lengths are 2.98 Å.
