Abstract
<jats:title>Abstract</jats:title><jats:p>We have synthesised and structurally characterised a new pentanuclear mixed‐valent cobalt cluster of formula [Co<jats:sup>II</jats:sup><jats:sub>3</jats:sub>Co<jats:sup>III</jats:sup><jats:sub>2</jats:sub>(OH)<jats:sub>2</jats:sub>(piv)<jats:sub>6</jats:sub>(L)<jats:sub>2</jats:sub>(H<jats:sub>2</jats:sub>O)<jats:sub>4</jats:sub>] (piv = trimethylacetate, H<jats:sub>2</jats:sub>L = salicylideneanthranillic acid) from reaction of a dinuclear cobalt pivalate precursor with a Schiff base type ligand under mild reaction conditions. The core structure can be conveniently described as two fused Co<jats:sub>3</jats:sub>–μ<jats:sub>3</jats:sub>–OH triangles with a strict unique sharing vertex point. A complete picture of the magnetic behaviour of this compound is presented. Through combined use of susceptibility, magnetisation, and EPR data as well as broken‐symmetry DFT calculations, we have supported the magnetic data that show weak and anisotropic exchange interaction between Co<jats:sup>II</jats:sup> ions affording an S<jats:sub>eff</jats:sub> = 1/2 ground state that is not completely isolated from the low‐lying excited doublets at low temperature. Under the optimum applied field of 2 kOe, a frequency‐dependent out‐of‐phase susceptibility signal can be observed below 4 K. However, no reliable relaxation rates could be extracted due to the narrow temperature range in which this behaviour was observed.</jats:p>
