| Abstract | Abstract Procedures have been developed for the synthesis of complexes containing the cations [Mn4O2(O2CR)4(L)2]2+ (R=Me, Et, Ph) (1) and [Mn4O2(MeO)3(O2CPh)2(L)2(MeOH)]2+ (2). Treatment of the corresponding [Mn3O(O2CR)6(py)3](ClO4) complex with the ligand 1,2-bis(bipyridine-6′-yl)ethane (L) in MeCN or MeOH leads to the formation of 1 and 2, respectively. Both complexes contain [Mn4O2] cores. Complex 1 has overall antiferromagnetic coupling resulting in a S=1 spin ground state. The metal centers in the core of complex 2 are also antiferromagnetically coupled, but in this case the spin ground state is S=7/2. Complex 2 also displays an out of phase signal in the ac magnetic susceptibility study, indicating it to be a new example of single molecule magnet (SMM). |
