Poly[?-aqua-aqua-{?-6-eth-oxy-2-[(2-isonicotinoylhydrazinyl-idene)meth-yl]phenolato-?O,N,O'}dioxidosodium-vanadate(V)].


ABSTRACT: The V(V) atom in the polymeric title compound, [NaV(C(15)H(13)N(3)O(3))O(2)(H(2)O)(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 Na(I) atom. The ligand simultaneously O,O'-chelates to the water-coordinated Na(I) atom; its coordination number is seven owing to an Na?N(pyrid-yl) 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-H?O and O-H?N hydrogen bonds.
