Yb2Ga is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to four equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing YbGa4 tetrahedra. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to five equivalent Ga(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms.

In the first Yb site, Yb(1) is bonded to four equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing YbGa4 tetrahedra. There are a spread of Yb(1)-Ga(1) bond distances ranging from 3.01-3.07 Å. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to five equivalent Ga(1) atoms. There are a spread of Yb(2)-Ga(1) bond distances ranging from 3.13-3.50 Å. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms.
