La3VH3O8 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. V(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. There are five 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 single-bond geometry to one La(1), two equivalent La(2), and one H(1) atom. In the third O site, O(3) is bonded to one La(1), two equivalent La(2), and one V(1) atom to form a mixture of corner and edge-sharing OLa3V tetrahedra.
