The crystal structure described by B6As is T-50 Boron-derived structured and crystallizes in the trigonal R-3m space group. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to three equivalent B(1) and three equivalent B(2) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to two equivalent B(2), three equivalent B(1), and one As(1) atom. As(1) is bonded in a distorted tetrahedral geometry to three equivalent B(2) and one As(1) atom. is represented by the CIF card [CIF]
