Abstract

Two Co₄-substituted sandwich-type polyoxometalates (H₂en)₉[Co₄(H₂O)₂(PW₉O₃₄)₂]{[Co(H₂O)₄][Co₄(H₂O)₂(PW₉O₃₄)₂]}·18H₂O (1) and (H₂en)₅[Co₄(H₂O)₂(H₃GeW₉O₃₄)₂]{[Co(H₂O)₄]₂[Co₄(H₂O)₂(H₂GeW₉O₃₄)₂]}·16H₂O (2) (en = ethylenediamine) have been hydrothermally synthesized and characterized by IR spectra, elemental analyses, thermogravimetric analyses, powder X-ray diffraction and single-crystal X-ray diffraction. Single-crystal structure analysis reveals that the molecules of 1 and 2 contain two Co₄-substituted sandwich-type polyoxoanions. This type of a molecular unit containing double polyoxoanions is very rare. From the viewpoint of supramolecular chemistry, the sandwich-type polyoxoanions in 1 and 2 can be further extended to 3-D frameworks via extensive hydrogen-bonding interactions.
