Rh2PtSi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Rh2PtSi cluster. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted single-bond geometry to one Pt(1) and one Si(1) atom. The Rh(1)-Pt(1) bond length is 1.09 Å. The Rh(1)-Si(1) bond length is 0.90 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Si(1) atom. The Rh(2)-Si(1) bond length is 1.51 Å. Pt(1) is bonded in a distorted single-bond geometry to one Rh(1) atom. Si(1) is bonded in a distorted single-bond geometry to one Rh(1) and one Rh(2) atom.
