Abstract
<jats:title>Abstract</jats:title><jats:p>A family of bisphenol‐containing ligands with XO<jats:sub>2</jats:sub> donor atoms, where X = S, Se, or N, yields [Ni<jats:sup>II</jats:sup>]<jats:sub>4</jats:sub> (<jats:bold>1</jats:bold>) and (<jats:bold>2</jats:bold>), [Ni<jats:sup>II</jats:sup>]<jats:sub>5</jats:sub> (<jats:bold>3</jats:bold>), and [Ni<jats:sup>II</jats:sup>]<jats:sub>6</jats:sub> (<jats:bold>4</jats:bold>) complexes. Complex <jats:bold>2</jats:bold>, <jats:bold>3</jats:bold>, and <jats:bold>4</jats:bold> have been structurally characterised by X‐ray diffraction. The compounds were characterised spectroscopically and by variable‐temperature (2−295 K), variable‐field (1, 4, and 7 T) magnetic susceptibility measurements. Analysis of the magnetic data shows predominant ferromagnetic interactions between the nickel centres (<jats:italic>S</jats:italic><jats:sub>Ni</jats:sub> = 1) indicating “high‐spin” ground states for <jats:bold>1</jats:bold>, <jats:bold>2</jats:bold>, and <jats:bold>3</jats:bold>, whereas complex <jats:bold>4</jats:bold> shows antiferromagnetic interactions. A plot of <jats:italic>J</jats:italic> vs. Ni−O−Ni angles for all structurally characterised Ni<jats:sub>4</jats:sub>O<jats:sub>4</jats:sub> cubane cores, including <jats:bold>2</jats:bold>, irrespective of their symmetry, shows a large variation of <jats:italic>J</jats:italic> values within a small range of Ni−O−Ni angles. A simple two‐<jats:italic>J</jats:italic> model was found to be adequate to describe the magnetic properties of the hexanuclear complex, <jats:bold>4</jats:bold>. (© Wiley‐VCH Verlag GmbH &amp; Co.
