Materials Data on B2S3 by Materials Project
B2S3 crystallizes in the trigonal R-3c space group. The structure is two-dimensional and consists of six B2S3 sheets oriented in the (0, 0, 1) direction. B3+ is bonded in a trigonal planar geometry to three equivalent S2- atoms. All B–S bond lengths are 1.82 Å. S2- is bonded in a bent 120 degrees geometry to two equivalent B3+ atoms.
