The compound described by Y11Ni4In9 crystallizes in the orthorhombic Cmmm space group. There are five inequivalent Y sites. In the first Y site, Y(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 Y site, Y(2) is bonded in a 10-coordinate geometry to four equivalent Ni(1), two equivalent In(3), and four equivalent In(1) atoms. In the third Y site, Y(3) is bonded in a distorted body-centered cubic geometry to four equivalent In(1) and four equivalent In(2) atoms. In the fourth Y site, Y(4) is bonded in a distorted body-centered cubic geometry to eight equivalent In(2) atoms. In the fifth Y site, Y(5) is bonded in a 10-coordinate geometry to four equivalent Ni(1), two equivalent In(3), and four equivalent In(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Y(1), two equivalent Y(2), two equivalent Y(5), one In(1), one In(2), and one In(3) atom. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to two equivalent Y(2), two equivalent Y(3), four equivalent Y(1), one Ni(1), and one In(1) atom. In the second In site, In(2) is bonded in a 10-coordinate geometry to two equivalent Y(1), two equivalent Y(3), two equivalent Y(4), two equivalent Y(5), one Ni(1), and one In(2) atom. In the third In site, In(3) is bonded to four equivalent Y(2), four equivalent Y(5), and four equivalent Ni(1) atoms to form face-sharing InY8Ni4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
