SrRu2Ga crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a distorted L-shaped geometry to one Ru(1) and one Ru(2) atom. The Sr(1)-Ru(1) bond length is 2.29 Å. The Sr(1)-Ru(2) bond length is 2.29 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 1-coordinate geometry to one Sr(1) and three equivalent Ga(1) atoms. There is one shorter (2.45 Å) and two longer (3.03 Å) Ru(1)-Ga(1) bond lengths. In the second Ru site, Ru(2) is bonded in a 1-coordinate geometry to one Sr(1) and three equivalent Ga(1) atoms. There is one shorter (2.57 Å) and two longer (3.13 Å) Ru(2)-Ga(1) bond lengths. Ga(1) is bonded in a 6-coordinate geometry to three equivalent Ru(1) and three equivalent Ru(2) atoms.
