title: Crystal structure of (2-formyl-phenolato-κ(2) O,O')oxido(2-{[(2-oxidoeth-yl)imino]-meth-yl}phenolato-κ(3) O,N,O')vanadium(V).
abstract: In the unsymmetrical title vanadyl complex, [V(C9H9NO2)(C7H5O2)O], one of the ligands (2-formyl-phenol) is disordered over two sets of sites, with an occupancy ratio of 0.55 (2):0.45 (2). The metal atom is hexa-coordinated, with a distorted octa-hedral geometry. The vanadyl O atom (which subtends the shortest V-O bond) occupies one of the apical positions and the remaining axial bond (the longest in the polyhedron) is provided by the (disordered) formyl O atoms. The basal plane is defined by the two phenoxide O atoms, the imino-alcoholic O and the imino N atom. The planes of the two benzene rings are almost perpendicular to each other, subtending an inter-planar angle of 84.1 (2)° between the major parts. The crystal structure features weak C-H⋯O and C-H⋯π inter-actions, forming a lateral arrangement of adjacent molecules.
