Materials Data on B by Materials Project

Abstract

B is T-50 Boron structured and crystallizes in the tetragonal P4_2/nnm space group. The structure is three-dimensional. there are five inequivalent B sites. In the first B site, B is bonded in a distorted trigonal pyramidal geometry to four equivalent B atoms. All B–B bond lengths are 1.70 Å. In the second B site, B is bonded in a 6-coordinate geometry to six B atoms. There are a spread of B–B bond distances ranging from 1.72–1.83 Å. In the third B site, B is bonded in a 6-coordinate geometry to six B atoms. There are a spread of B–B bond distances ranging from 1.71–1.82 Å. In the fourth B site, B is bonded in a 6-coordinate geometry to six B atoms. There is one shorter (1.74 Å) and two longer (1.80 Å) B–B bond length. In the fifth B site, B is bonded in a 6-coordinate geometry to six B atoms. There is one shorter (1.78 Å) and one longer (1.86 Å) B–B bond length.
