Re Hg Pt
RePtHg crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RePtHg clusters. Re(1) is bonded in a 1-coordinate geometry to one Hg(1) atom. The Re(1)-Hg(1) bond length is 2.51 Å. Pt(1) is bonded in a single-bond geometry to one Hg(1) atom. The Pt(1)-Hg(1) bond length is 0.27 Å. Hg(1) is bonded in a single-bond geometry to one Re(1) and one Pt(1) atom.
