Three new supramolecular compounds based on triethylenediamine and different polyoxometalates [WVI3VV3O19H]{[Cu(HDABCO)]2(H2O)} (1), [P2MoVI18O62][HDABCO]2[H2DABCO]2·12 H2O (2) and [MoVI7.5WVI0.5O27][Cu(HDABCO)]2·2 H3O·2 H2O (3) (DABCO=triethylenediamine) have been synthesized hydrothermally and characterized by IR, TG, XPS and X-ray diffraction analyses. Crystal structure analyses reveal that compound 1 exhibits a face-centered cubic packing motif, compound 2 displays a supramolecular structure constructed form the “chains” arranged hexagonally, compound 3 contains [Mo7.5W0.5O27]∞ chain decorated by [Cu(HDABCO)]2+ cations, which was then packed into a layer structure. These results show that the same organonitrogen combining with the different POMs will yield different supramolecular networks.
