Abstract: A series of four diaminoalkane templated vanadium oxide polymeric frameworks, [V2IVO8V2VO2](C2H10N2), [V2IVO8V2VO2](C3H12N2), [V4IVO10V2VO4](C4H14N2) and [V4IVO10V2VO4](C5H16N2), have been successfully prepared under hydrothermal conditions. The crystal structures are fully characterized revealing layered structures composed of common inorganic building units, namely {VIVO5} square pyramids and {VVO4} tetrahedra. The layer registries are different depending on the molecular structure of the diaminoalkanes, and can be accounted for by the organic-inorganic interface interactions. The analysis of hydrogen bonds indicates their important role in directing two- and three-dimensional structural architectures. The influences of different diaminoalkanes are also apparent in both thermogravimetric and complex magnetic behaviors, and are discussed in details. © 2007 Springer Science+Business Media, LLC.
