The material structure described by Pb3Ga2Ge4O14 crystallizes in the trigonal P321 space group. Ga(1) is bonded to one O(1) and three equivalent O(2) atoms to form GaO4 tetrahedra that share corners with three equivalent Ge(1)O4 tetrahedra. Pb(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form GeO4 tetrahedra that share corners with two equivalent Ge(2)O6 octahedra and corners with two equivalent Ga(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. In the second Ge site, Ge(2) is bonded to six equivalent O(3) atoms to form corner-sharing GeO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Ga(1) and three equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Ga(1), one Pb(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Pb(1), one Ge(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
