Abstract

Reactions of monovacant Dawson-/Keggin-polyoxoanions, formed in situ from trivacant Dawson-/Keggin-precursors, with copper complexes under hydrothermal conditions lead to three inorganic-organic hybrid polyoxotungstates [Cu(en)₂(H₂O)]₂{[Cu(en)₂(H₂O)]₂[Cu(en)₂]₄[Cu(en)₂][α₂-P₂W₁₇CuO₆₁]₂}·(OH)₂·12H₂O (1), [Cu(dap)₂][Cu(dap)₂(H₂O)]₂[α-PW₁₁CuO₃₉]·(OH)·2H₂O (2) and (H₂en)₂[α-PW₁₁CuO₃₉][Cu(en)₂(H₂O)₂]_0.5·1.5H₂O (3) (en = ethylenediamine and dap = 1,2-diaminopropane). X-ray structural analyses demonstrate that 1 exhibits the first zigzag 1-D chain arrangement constructed from mono-copper^II-substituted Dawson dimeric polyoxoanions [α₂-P₂W₁₇CuO₆₁]₂^16-linked by [Cu(en)₂]²⁺ bridges, whereas 2 and 3 display 1-D linear chain architectures made up of mono-copper^II-substituted Keggin polyoxoanions [α-PCuW₁₁O₃₉]^5- linked together via corner-sharing MO₆ octahedra (M = Cu or W).
