Materials Data on Sm(BC)2 by Materials Project
SmB2C2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Sm2+ is bonded in a body-centered cubic geometry to eight equivalent C4- atoms. All Sm–C bond lengths are 2.75 Å. B3+ is bonded in a distorted trigonal planar geometry to three equivalent C4- atoms. There is one shorter (1.53 Å) and two longer (1.61 Å) B–C bond length. C4- is bonded in a 3-coordinate geometry to four equivalent Sm2+ and three equivalent B3+ atoms.
