Abstract

The reaction of (NBu4n)[Mn8O6Cl6(O2CPh)(7)(H2O)(2)] with 2-(hydroxymethyl)pyridine (hmpH) or 2-(hydroxyethyl)pyridine (hepH) gives the (Mn2Mn10III)-Mn-II complexes [Mn12O8- Cl-4(O2CPh)(8)(hxp)(6)] [hxp(-) = hmp(-) (1) or hep(-) (2)]; these compounds are core isomers with markedly different magnetic properties, compound 1 having an S = 7 ground state and displaying strong out-of-phase ac susceptibility signals that establish it as a new class of single-molecule magnet, whereas compound 2 is a low-spin molecule with an S = 0 ground state.
