The compound described by LuB2C crystallizes in the tetragonal P4_2/mbc space group. Lu(1) is bonded in a 14-coordinate geometry to four equivalent B(1), six equivalent B(2), and four equivalent C(1) atoms. There are two inequivalent B sites. In the first B site, B(1) 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(2) 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(2), and two equivalent B(1) atoms. is represented by the CIF file [CIF]
