The material structure described by B is gamma plutonium structured and crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of four B clusters. There are five inequivalent B sites. In the first B site, B(1) is bonded in a 4-coordinate geometry to one B(2), one B(3), one B(4), and one B(5) atom. In the second B site, B(2) is bonded in a 5-coordinate geometry to one B(1), one B(3), one B(4), and two equivalent B(5) atoms. In the third B site, B(3) is bonded in a distorted trigonal non-coplanar geometry to one B(1), one B(2), and one B(4) atom. In the fourth B site, B(4) is bonded in a 4-coordinate geometry to one B(1), one B(2), one B(3), and one B(5) atom. In the fifth B site, B(5) is bonded in a 4-coordinate geometry to one B(1), one B(4), and two equivalent B(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
