Ga3Pb is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Ga(2) and four equivalent Pb(1) atoms to form a mixture of distorted edge, face, and corner-sharing GaGa4Pb4 tetrahedra. In the second Ga site, Ga(2) is bonded in a distorted q6 geometry to eight equivalent Ga(1) and two equivalent Pb(1) atoms. Pb(1) is bonded in a body-centered cubic geometry to two equivalent Ga(2) and eight equivalent Ga(1) atoms.

In the first Ga site, Ga(1) is bonded to four equivalent Ga(2) and four equivalent Pb(1) atoms to form a mixture of distorted edge, face, and corner-sharing GaGa4Pb4 tetrahedra. All Ga(1)-Ga(2) bond lengths are 3.10 Å. All Ga(1)-Pb(1) bond lengths are 3.10 Å. In the second Ga site, Ga(2) is bonded in a distorted q6 geometry to eight equivalent Ga(1) and two equivalent Pb(1) atoms. Both Ga(2)-Pb(1) bond lengths are 3.40 Å. Pb(1) is bonded in a body-centered cubic geometry to two equivalent Ga(2) and eight equivalent Ga(1) atoms.
