Lu5Ni2In4 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 8-coordinate geometry to two equivalent Ni(1), two equivalent In(2), and four equivalent In(1) atoms. In the second Lu site, Lu(2) is bonded in a 10-coordinate geometry to four equivalent Ni(1), two equivalent In(1), and four equivalent In(2) atoms. In the third Lu site, Lu(3) is bonded in a distorted body-centered cubic geometry to four equivalent In(1) and four equivalent In(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Lu(1), four equivalent Lu(2), one In(1), and two equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 9-coordinate geometry to two equivalent Lu(2), two equivalent Lu(3), four equivalent Lu(1), one Ni(1), and one In(2) atom. In the second In site, In(2) is bonded in a 11-coordinate geometry to two equivalent Lu(1), two equivalent Lu(3), four equivalent Lu(2), two equivalent Ni(1), and one In(1) atom.
