The neutral binuclear mol-ecule of the title complex, [V2(C15H12N2O2S)2(CH3O)2O2], exhibits inversion symmetry and consists of two oxidovanadium(V) (VO)(3+) fragments, each coordinated by a dianionic and O,N',O'-chelating N'-(1-benzoyl-prop-1-en-2-yl)thio-phene-2-carbohydrazidate ligand. The V(5+) cations are bridged by two asymmetrically bonding methano-late ligands [V-O = 1.8155 (12) and 2.3950 (13) Å] originating from the deprotonation of the methanol solvent. The coordination sphere of the V(V) atom is distorted octa-hedral, with the equatorial plane defined by the three donor atoms of the thio-phene-2-carbohydrazidate ligand and the O atom of a methano-late unit. The axial positions are occupied by the oxide group and the remaining methano-late ligand. The axially bound methano-late ligand shows a longer V-O bond length due to the trans influence caused by the tightly bonded oxide group. The packing of the complex mol-ecules is dominated by dispersion forces.
