Abstract

The reaction of (NBun4)[Mn8O6Cl6(O 2CPh)7(H2O)2] with 2-(hydroxymethyl)pyridine (hmpH) or 2-(hydroxyethyl)pyridine (hepH) gives the MnII2MnIII10 complexes [Mn12O8- Cl4(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.
