This paper describes the structure for a new complex of oxovanadium (IV) with H/sub 2/L. This compound was obtained by mixing warm aqueous solutions containing 1.0 g VOSO/sub 4/ .2H/sub 2/O and H/sub 2/L at room temperature. The coordinates and the individual temperature factors of the basis atoms in the structure VOLH/sub 2/O .H/sub 2/O are presented. It is shown that the vanadium atom in both complexes has a distorted octahedral environment. The geometrical isomerism is accompanied by differences in the conformations of the molecular ligand. Two geometrical isomers of a previously unknown type are concurrently present in the VOLH/sub 2/O structure. The formation of these isomers is made possible by the different arrangement of inequivalent branches of the organic ligand. This type of isomerism should be expected in the complexes of other metals with H/sub 2/L and in the coordination compounds of metals with other B-type tripod ligands.
