Lu2NiSn6 crystallizes in the orthorhombic Cmmm space group. Lu(1) is bonded in a 10-coordinate geometry to two equivalent Sn(2), two equivalent Sn(3), and six equivalent Sn(1) atoms. Ni(1) is bonded in a body-centered cubic geometry to four equivalent Sn(2) and four equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to six equivalent Lu(1) and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to two equivalent Lu(1) and two equivalent Ni(1) atoms. In the third Sn site, Sn(3) is bonded in a 4-coordinate geometry to two equivalent Lu(1) and two equivalent Ni(1) atoms.
