| Abstract: | Two new supramolecular compounds based on arsenic vanadates formulated as [H2As6V15O42(H2O)][Co(H2O)6]2·2H2O (1) and [H2As6V15O42(H2O)][Ni(H2O)6]2·2H2O (2) have been prepared by reacting V2O5, H2C2O4·2H2O, As2O3,·H2SO4, CoCl2·6H2O (NiSO4·6H2O) and enMe (enMe=1,2-diaminopropane) under mild hydrothermal conditions and characterized by elemental analyses, IR, ESR, XPS and single crystal X-ray diffraction analyses. Crystal structure analyses reveal that compounds 1 and 2 are isostructural and exhibit novel 2-D supramolecular layer structures constructed from arsenic-vanadium clusters and two different types of secondary building units (SBUs), respectively, the different SBUs are formed by joint of two adjacent [Co(H2O)6]2+ cations in compounds 1 and [Ni(H2O)6]2+ cations in 2, respectively. |
