(Na)2TcB is High Pressure Cadmuum Telluride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two disodium molecules and two TcB clusters. In each TcB cluster, Tc(1) is bonded in a distorted single-bond geometry to one B(1) atom. The Tc(1)-B(1) bond length is 1.61 Å. B(1) is bonded in a distorted single-bond geometry to one Tc(1) atom.
