Materials Data on Tc3B by Materials Project
Tc3B crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two Tc3B sheets oriented in the (0, 1, 0) direction. there are two inequivalent Tc1- sites. In the first Tc1- site, Tc1- is bonded in a 2-coordinate geometry to three equivalent B3+ atoms. There are two shorter (2.24 Å) and one longer (2.53 Å) Tc–B bond lengths. In the second Tc1- site, Tc1- is bonded in a distorted L-shaped geometry to two equivalent B3+ atoms. Both Tc–B bond lengths are 2.22 Å. B3+ is bonded in a 6-coordinate geometry to eight Tc1- atoms.
