Sm2Ni2In crystallizes in the orthorhombic Cmmm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), two equivalent Ni(1), and one In(1) atom. In(1) is bonded in a distorted q6 geometry to eight equivalent Sm(1) and two equivalent Ni(1) atoms.
Sm2Ni2In crystallizes in the orthorhombic Cmmm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent In(1) atoms. There are four shorter (2.87 Å) and two longer (3.00 Å) Sm(1)-Ni(1) bond lengths. All Sm(1)-In(1) bond lengths are 3.35 Å. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), two equivalent Ni(1), and one In(1) atom. Both Ni(1)-Ni(1) bond lengths are 2.41 Å. The Ni(1)-In(1) bond length is 2.89 Å. In(1) is bonded in a distorted q6 geometry to eight equivalent Sm(1) and two equivalent Ni(1) atoms.
