The crystal structure described by Sm2Ni2Ga crystallizes in the orthorhombic Immm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Ga(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), two equivalent Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to eight equivalent Sm(1) and four equivalent Ni(1) atoms to form a mixture of edge and face-sharing GaSm8Ni4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
