摘要
Two novel organic-inorganic composite phosphotungstates, [H9{Ce(α-PW11O39)2}Cu(en)2] · 6H2O (1) and H7[Cu(en)2{Er(α-PW11O39)2}Cu(en)2] · 12H2O (2) (en = ethylenediamine) have been synthesized by the hydrothermal reaction of the trivacant Keggin polyoxoanion [α-A-PW9O34]9- with CeIII or ErIII ions in the presence of Cu2+ ions and en, and structurally characterized by IR spectra, elemental analysis and thermogravimetric analysis. X-ray crystallographic analyses indicate that they are all built by sandwich-type [Ln(α-PW11O39)2]11- (Ln = CeIII, ErIII) polyoxoanions and [Cu(en)2]2+ cations generating infinite one-dimensional arrangements. To our knowledge, this 1-D chain structures constituted by mono-Ln sandwiched POM units and transition-metal complex cations are very rare.
