SmCoGa crystallizes in the monoclinic C2/m space group. Sm(1) is bonded in a 11-coordinate geometry to five equivalent Co(1) and six equivalent Ga(1) atoms. Co(1) is bonded in a 9-coordinate geometry to five equivalent Sm(1), one Co(1), and three equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), three equivalent Co(1), and one Ga(1) atom.
SmCoGa crystallizes in the monoclinic C2/m space group. Sm(1) is bonded in a 11-coordinate geometry to five equivalent Co(1) and six equivalent Ga(1) atoms. There are a spread of Sm(1)-Co(1) bond distances ranging from 2.90-3.06 Å. There are a spread of Sm(1)-Ga(1) bond distances ranging from 3.07-3.24 Å. Co(1) is bonded in a 9-coordinate geometry to five equivalent Sm(1), one Co(1), and three equivalent Ga(1) atoms. The Co(1)-Co(1) bond length is 2.34 Å. There are two shorter (2.52 Å) and one longer (2.60 Å) Co(1)-Ga(1) bond length. Ga(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), three equivalent Co(1), and one Ga(1) atom.
