Tc Hg Pt
TcPtHg crystallizes in the monoclinic Cm space group. Tc(1) is bonded to four equivalent Tc(1), one Pt(1), and one Hg(1) atom to form a mixture of corner and edge-sharing TcTc4HgPt octahedra. The corner-sharing octahedra are not tilted. All Tc(1)-Tc(1) bond lengths are 2.85 Å. The Tc(1)-Pt(1) bond length is 3.20 Å. The Tc(1)-Hg(1) bond length is 3.11 Å. Pt(1) is bonded in a single-bond geometry to one Tc(1) and 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 Tc(1) and one Pt(1) atom.
