Materials Data on AlBN2 by Materials Project

AlBN2 is Enargite-like structured and crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Al3+ is bonded to four equivalent N3- atoms to form AlN4 tetrahedra that share corners with four equivalent AlN4 tetrahedra and corners with eight equivalent BN4 tetrahedra. All Al–N bond lengths are 1.85 Å. B3+ is bonded to four equivalent N3- atoms to form BN4 tetrahedra that share corners with four equivalent BN4 tetrahedra and corners with eight equivalent AlN4 tetrahedra. All B–N bond lengths are 1.65 Å. N3- is bonded to two equivalent Al3+ and two equivalent B3+ atoms to form corner-sharing NAl2B2 tetrahedra.
