RuPt2Hg crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuPt2Hg clusters. Ru(1) is bonded in a distorted single-bond geometry to one Pt(2) and one Hg(1) atom. The Ru(1)-Pt(2) bond length is 1.24 Å. The Ru(1)-Hg(1) bond length is 0.30 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Hg(1) atom. The Pt(1)-Hg(1) bond length is 1.54 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Ru(1) atom. Hg(1) is bonded in a distorted single-bond geometry to one Ru(1) and one Pt(1) atom.
