Na Tc B B
NaTcB2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaTcB2 cluster. Na(1) is bonded in a single-bond geometry to one B(2) atom. The Na(1)-B(2) bond length is 1.52 Å. Tc(1) is bonded in a distorted linear geometry to one B(1) and one B(2) atom. The Tc(1)-B(1) bond length is 1.21 Å. The Tc(1)-B(2) bond length is 1.21 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted single-bond geometry to one Tc(1) atom. In the second B site, B(2) is bonded in a distorted L-shaped geometry to one Na(1) and one Tc(1) atom.
