Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The synthesis and characterisation of the hexanuclear copper(II) carboxylate complex [Cu(O₂CCHPhOC₂H₄OC₂H₄OCH₃)₂]₆ (<bold>1</bold>) is described. Single‐crystal X‐ray structure analysis reveals that the copper(II) ions are arranged in a six‐membered ring which adopts a chair‐like conformation. The copper(II) ions are bridged by μ₂‐ and μ₃‐coordinating carboxylates. The magnetic behavior of <bold>1</bold> was measured between 2 and 300 K, revealing at low temperature a weak antiferromagnetic interaction. The <italic>χ</italic>_M(<italic>T</italic>) dependency was fitted mathematically with one coupling constant <italic>J</italic>₁ and a paramagnetic impurity α.</p> </abstract>
