Materials Data on BN by Materials Project
BN crystallizes in the tetragonal I4/mmm space group. The structure is one-dimensional and consists of two BN ribbons oriented in the (0, 0, 1) direction. B3+ is bonded in a linear geometry to two equivalent N3- atoms. Both B–N bond lengths are 1.31 Å. N3- is bonded in a linear geometry to two equivalent B3+ atoms.
