摘要

A novel polyoxotungstate cluster (H₂en)_2.5H₉[Fe₆Ge₃W₂₄O₉₄(H₂O)₂] · 14H₂O (1) (en = ethylenediamine) has been hydrothermally synthesized and structurally characterized by IR, TGA and single-crystal X-ray diffraction. The polyoxoanion skeleton of 1 is composed of two tri-Fe^III substituted B-α-(Fe₃GeW₉O₄₀) Keggin units connected by an unique hexavacant GeW₆O₂₆ Keggin fragment, leading to the first Fe(III)-containing banana-shaped tungstogermanate. Magnetic measurements of 1 reveal that the exchange interactions within the trimetal clusters are antiferromagnetic.
