Materials Data on LuB2C by Materials Project

LuB2C crystallizes in the tetragonal P4_2/mbc space group. The structure is three-dimensional. Lu3+ is bonded in a 4-coordinate geometry to four equivalent C3- atoms. There are two shorter (2.54 Å) and two longer (2.55 Å) Lu–C bond lengths. There are two inequivalent B sites. In the first B site, B is bonded in a distorted water-like geometry to two equivalent C3- atoms. Both B–C bond lengths are 1.62 Å. In the second B site, B is bonded in a distorted single-bond geometry to one C3- atom. The B–C bond length is 1.59 Å. C3- is bonded in a 7-coordinate geometry to four equivalent Lu3+ and three B atoms.

Materials Data on LuB2C by Materials Project

LuB2C crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Lu3+ is bonded in a 4-coordinate geometry to four equivalent C3- atoms. There are two shorter (2.52 Å) and two longer (2.55 Å) Lu–C bond lengths. There are two inequivalent B sites. In the first B site, B is bonded in a distorted water-like geometry to two equivalent C3- atoms. There is one shorter (1.62 Å) and one longer (1.63 Å) B–C bond length. In the second B site, B is bonded in a distorted single-bond geometry to one C3- atom. The B–C bond length is 1.60 Å. C3- is bonded in a 7-coordinate geometry to four equivalent Lu3+ and three B atoms.
