The [VO(dl-meth)(NH2O)2]×H2O complex crystallizes in the monoclinic P21/c space group with a=5.8138(2), b=27.3496(8), c=7.5663(2) Å, beta=103.059(3)°, and Z=4 molecules per unit cell. 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.
