B is T-50 Boron structured and 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 distorted trigonal pyramidal geometry to four equivalent B(2) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to one B(1), one B(3), two equivalent B(4), and two equivalent B(5) atoms. In the third B site, B(5) is bonded in a 6-coordinate geometry to one B(2), one B(3), two equivalent B(4), and two equivalent B(5) atoms. In the fourth B site, B(3) is bonded in a 6-coordinate geometry to one B(2), one B(3), two equivalent B(4), and two equivalent B(5) atoms. In the fifth B site, B(4) is bonded in a 6-coordinate geometry to one B(2), one B(3), two equivalent B(4), and two equivalent B(5) atoms.

In the first B site, B(1) is bonded in a distorted trigonal pyramidal geometry to four equivalent B(2) atoms. All B(1)-B(2) bond lengths are 1.70 Å. In the second B site, B(2) is bonded in a 6-coordinate geometry to one B(1), one B(3), two equivalent B(4), and two equivalent B(5) atoms. The B(2)-B(3) bond length is 1.72 Å. Both B(2)-B(4) bond lengths are 1.82 Å. Both B(2)-B(5) bond lengths are 1.79 Å. In the third B site, B(5) is bonded in a 6-coordinate geometry to one B(2), one B(3), two equivalent B(4), and two equivalent B(5) atoms. The B(5)-B(3) bond length is 1.73 Å. There is one shorter (1.81 Å) and one longer (1.82 Å) B(5)-B(4) bond length. There is one shorter (1.70 Å) and one longer (1.82 Å) B(5)-B(5) bond length. In the fourth B site, B(3) is bonded in a 6-coordinate geometry to one B(2), one B(3), two equivalent B(4), and two equivalent B(5) atoms. The B(3)-B(3) bond length is 1.73 Å. Both B(3)-B(4) bond lengths are 1.80 Å. In the fifth B site, B(4) is bonded in a 6-coordinate geometry to one B(2), one B(3), two equivalent B(4), and two equivalent B(5) atoms. There is one shorter (1.78 Å) and one longer (1.86 Å) B(4)-B(4) bond length.
