Hg Os Pt Pt
OsPt2Hg crystallizes in the triclinic P1 space group. Os(1) is bonded in a single-bond geometry to one Pt(1) and two equivalent Hg(1) atoms. The Os(1)-Pt(1) bond length is 1.07 Å. There is one shorter (2.77 Å) and one longer (2.81 Å) Os(1)-Hg(1) bond length. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to one Os(1), one Pt(2), and two equivalent Hg(1) atoms. The Pt(1)-Pt(2) bond length is 1.48 Å. Both Pt(1)-Hg(1) bond lengths are 3.07 Å. In the second Pt site, Pt(2) is bonded in a 1-coordinate geometry to one Pt(1) and two equivalent Hg(1) atoms. Both Pt(2)-Hg(1) bond lengths are 3.07 Å. Hg(1) is bonded to two equivalent Os(1), two equivalent Pt(1), two equivalent Pt(2), and two equivalent Hg(1) atoms to form a mixture of distorted corner and edge-sharing HgHg2Os2Pt4 hexagonal bipyramids. Both Hg(1)-Hg(1) bond lengths are 2.83 Å.
