Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Three tungsten oxychloride clusters containing the nearly <italic>D</italic>_{3<italic>d</italic>} symmetric [(W₆O₆ⁱCl₆ⁱ)Cl₆^a]^{<italic>n</italic>–} (<italic>n</italic> = 2, 3) core were prepared from the cluster acid (H₅O₂)₂[W₆O₆Cl₁₂]<bold>·</bold>4H₂O and structurally characterized by single‐crystal X‐ray diffraction. The copper compound [Cu(H₂O)₄][W₆O₆Cl₁₂]<bold>·</bold>12H₂O releases water molecules to yield [Cu(H₂O)₆][W₆O₆Cl₁₂]. Both compounds are represented as diamagnetic clusters, having 14 electrons in W–W bonding states. Magnetic measurements on the calcium compound [Ca(H₂O)₇]₂[W₆O₆Cl₁₂]Cl revealed a paramagnetic cluster having 15 valence electrons.</p> </abstract>
