Mn Mn Tc B
TcMn2B crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TcMn2B cluster. Tc(1) is bonded in a single-bond geometry to one Mn(2) and one B(1) atom. The Tc(1)-Mn(2) bond length is 1.84 Å. The Tc(1)-B(1) bond length is 0.84 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one B(1) atom. The Mn(1)-B(1) bond length is 0.84 Å. In the second Mn site, Mn(2) is bonded in a 2-coordinate geometry to one Tc(1) and one B(1) atom. The Mn(2)-B(1) bond length is 1.72 Å. B(1) is bonded in a distorted water-like geometry to one Tc(1), one Mn(1), and one Mn(2) atom.
