The crystal structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
