The material structure described by SmNiIn is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded to two equivalent Ni(1), four equivalent Ni(2), two equivalent In(1), and four equivalent In(2) atoms to form a mixture of edge and face-sharing SmIn6Ni6 cuboctahedra. In the second Sm site, Sm(2) is bonded to two equivalent Ni(1), four equivalent Ni(2), two equivalent In(1), and four equivalent In(2) atoms to form a mixture of edge and face-sharing SmIn6Ni6 cuboctahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), one In(1), and two equivalent In(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(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 Sm(1), four equivalent Sm(2), one Ni(1), and two equivalent Ni(2) atoms. In the second In site, In(2) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), one Ni(1), and two equivalent Ni(2) atoms. is represented by the CIF card [CIF]
