Abstract: The structure of a new vanadium oxide compound, catena-poly[N,N'-bis(2-ammonioethyl)oxamide [dioxidovanadate--oxido-dioxidovanadate--oxido]], {(C₆H₁₆N₄O₂)[V₂O₆]}_n, exhibits helical vanadate chains, constructed from corner-sharing VO₄ tetrahedra. Adjacent chains are packed together by extensive hydrogen bonds involving the inorganic framework and the templating guest cations, which are centrosymmetric and occupy the free space between the stacks of chains.
