Materials Data on B6As by Materials Project
B6As is T-50 Boron-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent B sites. In the first 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 1.78–1.91 Å. In the second B site, B is bonded in a 6-coordinate geometry to five B and one As atom. Both B–B bond lengths are 1.73 Å. The B–As bond length is 2.01 Å. As is bonded in a distorted tetrahedral geometry to three equivalent B and one As atom. The As–As bond length is 2.41 Å.
