The material structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
