Sr Hg Hg Pt
SrPtHg2 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 2-coordinate geometry to three equivalent Pt(1) atoms. There are a spread of Sr(1)-Pt(1) bond distances ranging from 2.74-3.68 Å. Pt(1) is bonded to three equivalent Sr(1), two equivalent Hg(1), and two equivalent Hg(2) atoms to form a mixture of distorted edge and corner-sharing PtSr3Hg4 pentagonal bipyramids. There is one shorter (2.13 Å) and one longer (2.77 Å) Pt(1)-Hg(1) bond length. There is one shorter (2.13 Å) and one longer (2.77 Å) Pt(1)-Hg(2) bond length. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted single-bond geometry to two equivalent Pt(1) and one Hg(2) atom. The Hg(1)-Hg(2) bond length is 0.54 Å. In the second Hg site, Hg(2) is bonded in a distorted single-bond geometry to two equivalent Pt(1) and one Hg(1) atom.
