Ag2Ga is zeta silver zinc structured and crystallizes in the hexagonal P-62m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent Ag(1), six equivalent Ag(2), two equivalent Ga(1), and two equivalent Ga(2) atoms to form a mixture of distorted corner, edge, and face-sharing AgGa4Ag8 cuboctahedra. In the second Ag site, Ag(2) is bonded in a 13-coordinate geometry to two equivalent Ag(2), six equivalent Ag(1), one Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Ag(1), six equivalent Ag(2), and two equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 11-coordinate geometry to three equivalent Ag(2), six equivalent Ag(1), and two equivalent Ga(2) atoms.

Both Ag(1)-Ag(1) bond lengths are 2.91 Å. There are two shorter (2.96 Å) and four longer (2.99 Å) Ag(1)-Ag(2) bond lengths. Both Ag(1)-Ga(1) bond lengths are 2.69 Å. Both Ag(1)-Ga(2) bond lengths are 2.77 Å. In the second Ag site, Ag(2) is bonded in a 13-coordinate geometry to two equivalent Ag(2), six equivalent Ag(1), one Ga(2), and four equivalent Ga(1) atoms. Both Ag(2)-Ag(2) bond lengths are 2.91 Å. The Ag(2)-Ga(2) bond length is 2.80 Å. All Ag(2)-Ga(1) bond lengths are 2.87 Å. There are two inequivalent Ga sites.
