Materials Data on SmB2Rh2C by Materials Project
SmRh2B2C crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sm3+ is bonded in a square co-planar geometry to four equivalent C4- atoms. All Sm–C bond lengths are 2.72 Å. Rh+3.50+ is bonded to four equivalent B3- atoms to form a mixture of corner and edge-sharing RhB4 tetrahedra. All Rh–B bond lengths are 2.20 Å. B3- is bonded in a distorted single-bond geometry to four equivalent Rh+3.50+ and one C4- atom. The B–C bond length is 1.50 Å. C4- is bonded in a distorted linear geometry to four equivalent Sm3+ and two equivalent B3- atoms.
