The material structure described by La2WO6 crystallizes in the orthorhombic Pmn2_1 space group. There are four inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to one O(7), one O(8), two equivalent O(10), two equivalent O(4), and two equivalent O(6) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to one O(1), one O(10), one O(2), one O(4), one O(8), two equivalent O(3), and two equivalent O(5) atoms. In the third La site, La(3) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and two equivalent O(9) atoms to form distorted LaO7 pentagonal bipyramids that share  a cornercorner with one W(2)O6 octahedra, corners with two equivalent W(1)O6 octahedra, corners with two equivalent La(3)O7 pentagonal bipyramids, and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-49°. In the fourth La site, La(4) is bonded in a 7-coordinate geometry to two equivalent O(1), two equivalent O(10), two equivalent O(2), and two equivalent O(8) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(7), one O(8), two equivalent O(1), and two equivalent O(2) atoms to form distorted WO6 octahedra that share corners with four equivalent La(3)O7 pentagonal bipyramids. In the second W site, W(2) is bonded to one O(10), one O(3), one O(4), one O(5), one O(6), and one O(9) atom to form distorted WO6 octahedra that share  a cornercorner with one La(3)O7 pentagonal bipyramid and edges with two equivalent La(3)O7 pentagonal bipyramids. There are ten inequivalent O sites. In the first O site, O(5) is bonded to one La(3), two equivalent La(2), and one W(2) atom to form a mixture of edge and corner-sharing OLa3W tetrahedra. In the second O site, O(6) is bonded in a 3-coordinate geometry to one La(1), one La(3), and one W(2) atom. In the third O site, O(7) is bonded in a bent 150 degrees geometry to one La(1) and one W(1) atom. In the fourth O site, O(8) is bonded in a 6-coordinate geometry to one La(1), two equivalent La(2), two equivalent La(4), and one W(1) atom. In the fifth O site, O(9) is bonded in a distorted trigonal planar geometry to two equivalent La(3) and one W(2) atom. In the sixth O site, O(1) is bonded to one La(2), one La(3), one La(4), and one W(1) atom to form a mixture of distorted edge and corner-sharing OLa3W trigonal pyramids. In the seventh O site, O(10) is bonded to one La(1), one La(2), one La(4), and one W(2) atom to form a mixture of distorted edge and corner-sharing OLa3W tetrahedra. In the eighth O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one La(2), one La(3), one La(4), and one W(1) atom. In the ninth O site, O(3) is bonded to one La(3), two equivalent La(2), and one W(2) atom to form a mixture of distorted edge and corner-sharing OLa3W tetrahedra. In the tenth O site, O(4) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one W(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
