title: cis-Dioxido[N'-(2-oxidobenzyl-idene)pyridinium-4-carbohydrazidato-κO,N',O']vanadium(V).
abstract: The title Schiff base complex, [V(C(13)H(10)N(3)O(2))O(2)], features a square-pyramidal coordination geometry defined by the O,N',O'-donors of the tridentate Schiff base ligand and two oxide O atoms; one oxide O atom occupies the apical position. In the crystal, pyridinium-oxide N-H⋯O hydrogen bonds lead to zigzag supra-molecular chains with a flattened topology along [101]. The investigated crystal was twinned by nonmerohedry; the minor component refined to 18.5 (5)%.
