The material structure described by Lu2(NiB2)3 crystallizes in the orthorhombic Cmmm space group. Lu(1) is bonded in a 18-coordinate geometry to two equivalent Ni(2), four equivalent Ni(1), four equivalent B(1), and eight equivalent B(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent Lu(1), two equivalent Ni(2), two equivalent B(1), and four equivalent B(2) atoms to form distorted NiLu4Ni2B6 cuboctahedra that share corners with four equivalent Ni(2)Lu4Ni4B4 cuboctahedra, corners with six equivalent Ni(1)Lu4Ni2B6 cuboctahedra, edges with three equivalent Ni(1)Lu4Ni2B6 cuboctahedra, faces with two equivalent Ni(2)Lu4Ni4B4 cuboctahedra, and faces with three equivalent Ni(1)Lu4Ni2B6 cuboctahedra. In the second Ni site, Ni(2) is bonded to four equivalent Lu(1), four equivalent Ni(1), and four equivalent B(2) atoms to form distorted NiLu4Ni4B4 cuboctahedra that share corners with eight equivalent Ni(1)Lu4Ni2B6 cuboctahedra, faces with two equivalent Ni(2)Lu4Ni4B4 cuboctahedra, and faces with four equivalent Ni(1)Lu4Ni2B6 cuboctahedra. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to four equivalent Lu(1), two equivalent Ni(1), one B(1), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Lu(1), one Ni(2), two equivalent Ni(1), one B(1), and one B(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
