Abstract

A new supramolecular compound,(C6NO2H6)6[α-P2W18O62]·10H2O,was synthesized by the assembly of the Dawson-type polyoxometalate and isonicotinic acid.It was structurally characterized by elemental analysis,IR spectrum,thermal gravimetric analysis and X-ray single crystal diffraction analysis.X-ray crystallographic study showed that the 3D supramolecular structure was constructed by electrostatic attractions between the [α-P2W18O62]6-polyoxoanions and the protonated isonicotinic acid cations,and extensive hydrogen bonds interactions.Furthermore,the electrochemical behavior and UV spectrum of the compound were studied.
