Abstract: The VV atom in the polymeric title compound, [NaV(C15H13N3O3)O2(H2O)2]n, is O,N,O'-chelated by the Schiff base dianion and is five-coordinated in a trigonal-bipramidal coordination geometry. The oxide O atoms occupy the equatorial sites and one oxide O atom is connected to the NaI atom. The ligand simultaneously O,O'-chelates to the water-coordinated NaI atom; its coordination number is seven owing to an NaNpyridyl bond. The two independent formula units, which are disposed about a false center of inversion, are connected into a layer. Adjacent layers are consolidated into a three-dimensional network by O-HO and O-HN hydrogen bonds.
