Abstract

Two types of new polyoxometalates (POMs) based on circular P ₈W₄₈ clusters with different tetralanthanide (Ln) clusters and octamanganese centers, [K(H₂O)₂]₄[K ₄(μ-H₂O)₄(H₂O)₄] ₂{[Ln₂(μ-OH)₄(H₂O) _x]₂(H₂₄P₈W₄₈O ₁₈₄)}·yH₂O [Ln = Nd (1), Sm (2), Tb (3)] and [K(H₂O)₂]₄[K₄(μ-H ₂O)₈]₂[K(H₂O)]₈{[Mn ₈(H₂O)₁₆](H₄P₈W ₄₈O₁₈₄)}·36H₂O (4) have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, thermogravimetry (TG), and powder XRD. Compounds 1-3 are the first series of Ln-containing P ₈W₄₈-based POMs that use P₂W₁₂O ₄₈^14- as the precursor; previously known P ₈W₄₈-based POMs used P₈W₄₈O ₁₈₄^40- as the precursor. In 4, eight manganese ions were incorporated. Owing to the different radii of the Ln and Mn ions, the four large Ln ions are divided into two {Ln₂} clusters located on two sides of the cavity of the P₈W₄₈ wheel in 1-3, but the eight small manganese ions in 4 only bond to the inside of the P₈W₄₈ wheel and do not form manganese clusters. The magnetic properties of 3 are discussed.
