The material structure described by Ca3Ga3Ge3O14 crystallizes in the trigonal P321 space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Ga(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form GaO4 tetrahedra that share corners with two equivalent Ge(2)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 64°. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(3) and three equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent Ga(1)O4 tetrahedra. In the second Ge site, Ge(2) is bonded to six equivalent O(2) atoms to form GeO6 octahedra that share corners with six equivalent Ga(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ca(1), one Ga(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ca(1), one Ga(1), and one Ge(2) atom. In the third O site, O(3) is bonded to three equivalent Ca(1) and one Ge(1) atom to form distorted corner-sharing OCa3Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
