The structure described by B crystallizes in the monoclinic C2/m space group. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to two equivalent B(2), two equivalent B(3), and two equivalent B(4) atoms. In the second B site, B(2) is bonded in a 7-coordinate geometry to one B(1), two equivalent B(2), two equivalent B(3), and two equivalent B(4) atoms. In the third B site, B(3) is bonded in a 6-coordinate geometry to two equivalent B(1) and four equivalent B(2) atoms. In the fourth B site, B(4) is bonded in a 4-coordinate geometry to one B(1), one B(4), and two equivalent B(2) atoms. is represented by the CIF card [CIF]
