The compound described by ZnOLa2O3 crystallizes in the orthorhombic Pnma space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing LaO6 octahedra. In the second La site, La(2) is bonded in a 7-coordinate geometry to one O(2), one O(3), two equivalent O(4), and three equivalent O(1) atoms. Zn(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites.

In the second O site, O(2) is bonded to one La(2), two equivalent La(1), and one Zn(1) atom to form distorted OLa3Zn trigonal pyramids that share  a cornercorner with one O(1)La4 tetrahedra, corners with two equivalent O(3)La3Zn tetrahedra, corners with five equivalent O(4)La3Zn tetrahedra, corners with two equivalent O(2)La3Zn trigonal pyramids, edges with two equivalent O(3)La3Zn tetrahedra, and edges with two equivalent O(1)La4 tetrahedra.
