Na Tc Tc Pt
NaTc2Pt is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaTc2Pt clusters. Na(1) is bonded in a distorted single-bond geometry to two equivalent Tc(1) and one Pt(1) atom. Both Na(1)-Tc(1) bond lengths are 1.36 Å. The Na(1)-Pt(1) bond length is 0.79 Å. Tc(1) is bonded in a 3-coordinate geometry to one Na(1), one Tc(1), and one Pt(1) atom. The Tc(1)-Tc(1) bond length is 0.79 Å. The Tc(1)-Pt(1) bond length is 1.36 Å. Pt(1) is bonded in a single-bond geometry to one Na(1) and two equivalent Tc(1) atoms.
