The material structure described by PbGa2O4 crystallizes in the triclinic P1 space group. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(1), one O(2), one O(6), and one O(8) atom to form corner-sharing GaO4 tetrahedra. In the second Ga site, Ga(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form corner-sharing GaO4 tetrahedra. In the third Ga site, Ga(3) is bonded to one O(1), one O(2), one O(7), and one O(8) atom to form corner-sharing GaO4 tetrahedra. In the fourth Ga site, Ga(4) is bonded to one O(3), one O(4), one O(5), and one O(7) atom to form corner-sharing GaO4 tetrahedra. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), one O(6), and one O(8) atom. In the second Pb site, Pb(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(4), one O(5), and one O(7) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Ga(1), one Ga(3), one Pb(1), and one Pb(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ga(1), one Ga(3), and one Pb(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ga(2), one Ga(4), and one Pb(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one Ga(2), one Ga(4), one Pb(1), and one Pb(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Ga(2), one Ga(4), and one Pb(2) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Ga(1), one Ga(2), and one Pb(1) atom. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one Ga(3), one Ga(4), and one Pb(2) atom. In the eighth O site, O(8) is bonded in a distorted trigonal planar geometry to one Ga(1), one Ga(3), and one Pb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
