N2 - The thermally more stable isomer of the title complex, {2,2′-[(RS,SR)-2,3-butanediylbis (nitrilomethylidene)]diphenolato-O,N,N′,O′}oxovanadium(IV), [VO(C18H18N2O2)] or [VO(sal-meso-bn)] [H2sal-meso-bn is (RS,SR)-N,N′-bis(salicylidene)-2,3-butanediamine], in the solid state, has been determined to be the exo isomer. The two methyl groups of the central diamine moiety in the Schiff base ligand are on the same side of the N2Ooxo plane of the VN2O3 square pyramid as the oxo ligand. The V=O distance is 1.595 (2) Å, and the V atom is displaced by 0.50 (1) Å toward the oxo ligand from the N2O2 basal plane. There is an intermolecular V⋯Osalicyl close contact of 2.972 (2) Å, which is trans to the V=O bond.
