La3SbZn3Ge2O14 crystallizes in the trigonal P321 space group. La(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Zn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted ZnO4 trigonal pyramids that share corners with two equivalent Sb(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 66°. Ge(1) is bonded to one O(3) and three equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent Zn(1)O4 trigonal pyramids. Sb(1) is bonded to six equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Zn(1)O4 trigonal pyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent La(1), one Zn(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one La(1), one Zn(1), and one Sb(1) atom. In the third O site, O(3) is bonded to three equivalent La(1) and one Ge(1) atom to form distorted corner-sharing OLa3Ge tetrahedra.
