Materials Data on LaB2Ir2C by Materials Project
LaIr2B2C crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. La3+ is bonded in a square co-planar geometry to four equivalent C4- atoms. All La–C bond lengths are 2.75 Å. Ir+3.50+ is bonded to four equivalent B3- atoms to form a mixture of edge and corner-sharing IrB4 tetrahedra. All Ir–B bond lengths are 2.24 Å. B3- is bonded in a distorted single-bond geometry to four equivalent Ir+3.50+ and one C4- atom. The B–C bond length is 1.52 Å. C4- is bonded in a distorted linear geometry to four equivalent La3+ and two equivalent B3- atoms.
