Abstract

The reaction between manganese nitrate and <i>N,Nʹ</i>-(±)-ethylene-bis(salicylicyclohexanediaminate) ((±)-salcy) in dilute lacunary polyoxoanion [PW<sub>9</sub>O<sub>34</sub>]<sup>9−</sup> solution led to isolation of a new Mn-dimer, [Mn((±)-salcy)(N<sub>3</sub>)]<sub>2</sub> (<b>1</b>). Structural analysis indicates that <b>1</b> represents the first salcy-based Mn-dimer complex. Magnetic susceptibility studies reveal that <b>1</b> shows single-molecule magnet (SMM) behavior from 2 to 5 K.
