LaAg2Ga crystallizes in the monoclinic Cm space group. La(1) is bonded in a 2-coordinate geometry to one Ag(1), two equivalent Ag(2), and one Ga(1) atom. The La(1)-Ag(1) bond length is 1.23 Å. There is one shorter (3.09 Å) and one longer (4.12 Å) La(1)-Ag(2) bond length. The La(1)-Ga(1) bond length is 1.41 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted L-shaped geometry to one La(1) and one Ga(1) atom. The Ag(1)-Ga(1) bond length is 0.69 Å. In the second Ag site, Ag(2) is bonded in a 7-coordinate geometry to two equivalent La(1), four equivalent Ag(2), and one Ga(1) atom. All Ag(2)-Ag(2) bond lengths are 3.50 Å. The Ag(2)-Ga(1) bond length is 2.70 Å. Ga(1) is bonded in a distorted single-bond geometry to one La(1), one Ag(1), and one Ag(2) atom.
