Abstract

A series of complexes constructed from multinuclear copper clusters and polyoxometalates, namely, [Cu₆(PO₄)2(H₂O) ₂(bpy)₆](H₃O)₂[P₂W ₁₈O₆₂](bpy = 2,2′-bipyridine, 1), [Cu ₆(PO₄)₂(H₂O)₄(phen) ₆](H₂O)₂[P₂W₁₈O ₆₂] (phen = 1,10-phenanthroline, 2), [Cu₂Cl(phen) ₄][PW₁₂O₄₀] (3), [Cu₄(HPO ₄)₂(H₂O)₄(phen)₄](H ₃O)₂[PV₃W₉O₄₀] (4), and [Cu₄(HPO₄)2(H₂O)₂(bpy) ₄](H₂O)₂[PVW₁₁O₄₀] (5), have been successfully synthesized in situ under hydrothermal conditions via changing the ligand, adjusting the pH value, and introducing low-valence metal (V^5-). Complex 1 represents the first example of ID linear chain constructed from alternating mixed-valence hexacopper (four Cu²⁺ and two Cu⁺) clusters and Wells - Dawson type polyoxometalates. Complex 2 exhibits an unprecedented 2D layer network based on hexacopper phosphate and Wells - Dawson type polyoxometalates. Complex 3 constructed from dicopper coordination compounds and Keggin polyoxometalates, was obtained from the similar hydrothermal treatment of 2 at much lower pH value. Complexes 4-5 represent the first two examples of ID linear chain constructed from alternating tetracopper phosphate cations and V^5--substituted Keggin type polyoxometalates. The magnetic properties of the complexes have been investigated between 2 and 300 K.
