SrCd2Ga crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a distorted single-bond geometry to eight equivalent Cd(1) and one Ga(1) atom. There are a spread of Sr(1)-Cd(1) bond distances ranging from 2.79-4.07 Å. The Sr(1)-Ga(1) bond length is 2.19 Å. Cd(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), three equivalent Cd(1), and two equivalent Ga(1) atoms. There is one shorter (2.19 Å) and two longer (3.48 Å) Cd(1)-Cd(1) bond lengths. There is one shorter (2.79 Å) and one longer (3.04 Å) Cd(1)-Ga(1) bond length. Ga(1) is bonded in a distorted single-bond geometry to one Sr(1) and four equivalent Cd(1) atoms.
