LuB2C crystallizes in the orthorhombic Pbam space group. Lu(1) is bonded in a 14-coordinate geometry to four equivalent B(2), six equivalent B(1), and four equivalent C(1) atoms. There are two inequivalent B sites. In the first B site, B(2) is bonded in a distorted water-like geometry to four equivalent Lu(1) and two equivalent C(1) atoms. In the second B site, B(1) is bonded in a distorted single-bond geometry to six equivalent Lu(1) and one C(1) atom. C(1) is bonded in a 3-coordinate geometry to four equivalent Lu(1), one B(1), and two equivalent B(2) atoms.
LuB2C crystallizes in the orthorhombic Pbam space group. Lu(1) is bonded in a 14-coordinate geometry to four equivalent B(2), six equivalent B(1), and four equivalent C(1) atoms. There are two shorter (2.58 Å) and two longer (2.59 Å) Lu(1)-B(2) bond lengths. There are two shorter (2.70 Å) and four longer (2.71 Å) Lu(1)-B(1) bond lengths. There are two shorter (2.51 Å) and two longer (2.54 Å) Lu(1)-C(1) bond lengths. There are two inequivalent B sites. In the first B site, B(2) is bonded in a distorted water-like geometry to four equivalent Lu(1) and two equivalent C(1) atoms. There is one shorter (1.61 Å) and one longer (1.63 Å) B(2)-C(1) bond length. In the second B site, B(1) is bonded in a distorted single-bond geometry to six equivalent Lu(1) and one C(1) atom.
