Sm2Ni2Cd crystallizes in the orthorhombic Cmmm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Cd(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), two equivalent Ni(1), and one Cd(1) atom. Cd(1) is bonded in a distorted q6 geometry to eight equivalent Sm(1) and two equivalent Ni(1) atoms.
Sm2Ni2Cd crystallizes in the orthorhombic Cmmm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Cd(1) atoms. There are four shorter (2.87 Å) and two longer (2.97 Å) Sm(1)-Ni(1) bond lengths. All Sm(1)-Cd(1) bond lengths are 3.36 Å. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), two equivalent Ni(1), and one Cd(1) atom. Both Ni(1)-Ni(1) bond lengths are 2.41 Å. The Ni(1)-Cd(1) bond length is 2.92 Å. Cd(1) is bonded in a distorted q6 geometry to eight equivalent Sm(1) and two equivalent Ni(1) atoms.
