Materials Data on ThB2Rh2C by Materials Project
ThRh2B2C crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Th4+ is bonded in a square co-planar geometry to four equivalent C4- atoms. All Th–C bond lengths are 2.75 Å. Rh3+ is bonded to four equivalent B3- atoms to form a mixture of edge and corner-sharing RhB4 tetrahedra. All Rh–B bond lengths are 2.21 Å. B3- is bonded in a distorted single-bond geometry to four equivalent Rh3+ and one C4- atom. The B–C bond length is 1.52 Å. C4- is bonded in a distorted linear geometry to four equivalent Th4+ and two equivalent B3- atoms.
