| Abstract: | The synthesis and characterisation of the hexanuclear copper(II) carboxylate complex [Cu(O2CCHPhOC2H4OC2H4OCH3)2]6 ( 1 ) 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 1 was measured between 2 and 300 K, revealing at low temperature a weak antiferromagnetic interaction. The χM(T) dependency was fitted mathematically with one coupling constant J1 and a paramagnetic impurity α. |
