Materials Data on LaNi2B2C by Materials Project
LaNi2B2C crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. La2+ is bonded in a square co-planar geometry to four equivalent C4- atoms. All La–C bond lengths are 2.67 Å. Ni1+ is bonded to four equivalent B atoms to form a mixture of distorted corner and edge-sharing NiB4 tetrahedra. All Ni–B bond lengths are 2.12 Å. B is bonded in a distorted single-bond geometry to four equivalent Ni1+ and one C4- atom. The B–C bond length is 1.49 Å. C4- is bonded in a distorted linear geometry to four equivalent La2+ and two equivalent B atoms.
