Tc Bi Bi Pt
TcPtBi2 crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one TcPtBi2 cluster. Tc(1) is bonded in a distorted single-bond geometry to one Bi(1) atom. The Tc(1)-Bi(1) bond length is 1.94 Å. Pt(1) is bonded in a distorted single-bond geometry to one Bi(2) atom. The Pt(1)-Bi(2) bond length is 2.31 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 2-coordinate geometry to one Tc(1) and one Bi(2) atom. The Bi(1)-Bi(2) bond length is 1.60 Å. In the second Bi site, Bi(2) is bonded in a distorted bent 120 degrees geometry to one Pt(1) and one Bi(1) atom.
