Lu3BC3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 6-coordinate geometry to one B(1), one C(2), and four equivalent C(1) atoms. In the second Lu site, Lu(2) is bonded to two equivalent C(1) and four equivalent C(2) atoms to form a mixture of corner and edge-sharing LuC6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°. B(1) is bonded in a linear geometry to two equivalent Lu(1) and two equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to one Lu(2), four equivalent Lu(1), and one B(1) atom. In the second C site, C(2) is bonded to two equivalent Lu(1) and four equivalent Lu(2) atoms to form a mixture of corner and edge-sharing CLu6 octahedra. The corner-sharing octahedral tilt angles range from 0-2°.
