Ionothermal synthesis and characterization of two polyoxometalate-based supramolecules

Abstract

Two novel 3D supramolecular architectures with hexamolybdate and phosphotungstate anions were synthesized under ionothermal conditions. The structures were named as [Cu^I(L1)₂]₂L2[Mo₆O₁₉](1) and [Cu^I(L3)₂]_2.5· H_0.5[PW₁₂O₄₀]·H₂O(2)(L1=2,2′-bipyridine, L2=4,4′-bipyridine, L3=2,2′–biimidazole) and characterized via Fourier transform infrared spectroscopy(FTIR) and FT-Raman spectroscopy analyses. Single-crystal X-ray diffraction analysis revealed that the two compounds crystallized in the space group P $\bar 1$ and were constructed through hydrogen bonding.
