The material structure described by B is T-50 Boron-like structured and crystallizes in the tetragonal P4_2/nnm space group. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to one B(3), one B(4), two equivalent B(1), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to one B(3), one B(4), two equivalent B(1), and two equivalent B(2) atoms. In the third B site, B(4) is bonded in a 6-coordinate geometry to one B(3), one B(4), two equivalent B(1), and two equivalent B(2) atoms. In the fourth B site, B(3) is bonded in a 5-coordinate geometry to one B(4), two equivalent B(1), and two equivalent B(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
