Materials Data on B2(CN2)3 by Materials Project

Abstract

B2(CN2)3 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two B2(CN2)3 sheets oriented in the (0, 0, 1) direction. B3+ is bonded in a trigonal planar geometry to three N3- atoms. All B–N bond lengths are 1.43 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.22 Å. In the second C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. Both C–N bond lengths are 1.22 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a bent 150 degrees geometry to one B3+ and one C4+ atom. In the second N3- site, N3- is bonded in a bent 150 degrees geometry to one B3+ and one C4+ atom. In the third N3- site, N3- is bonded in a bent 150 degrees geometry to one B3+ and one C4+ atom.
