Abstract	Three new organic–inorganic hybrid compounds H[Cu$^{I}$(dafo)$_{2}$]$_{3}${[Cu$^{I}$(dafo)$_{2}$]$_{2}$P$_{2}$W$_{18}$O$_{62}$} · H$_{2}$O (1), [Cu$^{I}$(dafo)$_{2}$]$_{3}$PMo$_{12}$O$_{40}$ (2) and [Cu$^{I}$(dafo)$_{2}$]$_{4}$SiW$_{12}$O$_{40}$ (3) (dafo = 4, 5-diazafluoren-9-one) have been hydrothermally synthesized and characterized by IR, TG and CV. Compound 1 exhibits a 3D supramolecular framework based on weak interactions between bisupported Dawson structure P$_{2}$W$_{18}$O$_{62}$ $^{6−}$ units and copper-complex fragments. With the aid of π–π stacking and hydrogen bonding interactions, a 1D supramolecular framework accommodating polyoxometalate (POM) anions is generated in 2. Compound 3 has similar fundamental units as 2, but the units are assembled in a different way. The distinction of their structures indicates that the POMs are the key factor in determining the frameworks of the final products. The electrochemical properties of these compounds have been studied using bulk-modified carbon paste electrodes.
