The structure described by B crystallizes in the tetragonal P4_2/nnm space group. There are five inequivalent B sites. In the first B site, B(1) is bonded in a 5-coordinate geometry to one B(4), two equivalent B(2), and two equivalent B(3) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to one B(1), one B(4), two equivalent B(2), and two equivalent B(3) atoms. In the third B site, B(3) is bonded in a 7-coordinate geometry to one B(1), one B(4), one B(5), two equivalent B(2), and two equivalent B(3) atoms. In the fourth B site, B(4) is bonded in a 6-coordinate geometry to one B(1), one B(4), two equivalent B(2), and two equivalent B(3) atoms. In the fifth B site, B(5) is bonded in a 8-coordinate geometry to eight equivalent B(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
