The crystal structure described by Lu4Ni13C4 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 14-coordinate geometry to two equivalent Ni(1), two equivalent Ni(3), two equivalent Ni(5), four equivalent Ni(2), and four equivalent Ni(4) atoms. In the second Lu site, Lu(2) is bonded in a 15-coordinate geometry to one Ni(5), two equivalent Ni(3), four equivalent Ni(2), four equivalent Ni(4), and four equivalent C(2) atoms. There are five inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent Lu(1), four equivalent Ni(4), and four equivalent Ni(5) atoms to form NiLu4Ni8 cuboctahedra that share corners with four equivalent C(1)Ni6 octahedra and faces with two equivalent Ni(1)Lu4Ni8 cuboctahedra. The corner-sharing octahedral tilt angles are 34°. In the second Ni site, Ni(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Lu(1), two equivalent Lu(2), one C(1), and one C(2) atom. In the third Ni site, Ni(3) is bonded in a linear geometry to two equivalent Lu(1), two equivalent Lu(2), and two equivalent C(1) atoms. In the fourth Ni site, Ni(4) is bonded in a single-bond geometry to two equivalent Lu(1), two equivalent Lu(2), one Ni(1), two equivalent Ni(5), and one C(1) atom. In the fifth Ni site, Ni(5) is bonded in a 9-coordinate geometry to one Lu(2), two equivalent Lu(1), two equivalent Ni(1), and four equivalent Ni(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to two equivalent Ni(2), two equivalent Ni(3), and two equivalent Ni(4) atoms to form CNi6 octahedra that share corners with two equivalent Ni(1)Lu4Ni8 cuboctahedra and corners with two equivalent C(1)Ni6 octahedra. The corner-sharing octahedra are not tilted. In the second C site, C(2) is bonded in a 7-coordinate geometry to four equivalent Lu(2), two equivalent Ni(2), and one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
