The structure described by LaV3O9 crystallizes in the monoclinic P2_1/m space group. La(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(5), and two equivalent O(3) atoms to form corner-sharing VO4 tetrahedra. In the second V site, V(2) is bonded to one O(2), one O(4), one O(6), and two equivalent O(3) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent V(1)O4 tetrahedra,  a cornercorner with one V(2)O5 trigonal bipyramid, and  an edgeedge with one V(2)O5 trigonal bipyramid. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one La(1) and one V(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one La(1) and two equivalent V(2) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one V(1) and two equivalent V(2) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one La(1) and one V(2) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to two equivalent La(1) and one V(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one La(1) and one V(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
