Ta Ta Tc Pt Pt
Ta2TcPt2 is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ta2TcPt2 clusters. Ta(1) is bonded in a distorted single-bond geometry to one Ta(1), one Tc(1), and one Pt(2) atom. The Ta(1)-Ta(1) bond length is 0.11 Å. The Ta(1)-Tc(1) bond length is 0.76 Å. The Ta(1)-Pt(2) bond length is 2.06 Å. Tc(1) is bonded in a distorted single-bond geometry to two equivalent Ta(1) and one Pt(1) atom. The Tc(1)-Pt(1) bond length is 0.19 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Tc(1) atom. In the second Pt site, Pt(2) is bonded in a 2-coordinate geometry to two equivalent Ta(1) atoms.
