The crystal and molecular structure of the [VO(DLmeth)( NH2O)2]・H2O complex has been determined by X-ray diffraction methods (monoclinic, P21/c with a = 5.8138(2), b = 27.3496(8), c = 7.5663(2) A° , β = 103.059(3)◦, and Z = 4). The vanadium(V) cation is in a pentagonal bipyramidal environment axially coordinated to the oxo group and equatorially to two hydroxylamido groups in a side-on fashion. The fifth equatorial binding site and the other apical position are occupied by an N and an O atom, respectively, from the methioninate anion acting as a bidentate ligand.
