Abstract
The reaction of salicylaldoxime (H2salox) with MnCl 2·4H2O and NEt4OH in MeOH affords the trinuclear manganese complex (NEt4)[Mn3O(salox) 3(MeOH)2(H2O)2Cl2] ·MeOH (1·MeOH). A similar reaction of 1·MeOH was carried out using MnBr2·4H2O to obtain the hexanuclear manganese complex (NEt4)3{NaBr2[Mn 3O(salox)3(H2O)4Br2] 2} (2). The reaction of 2-hydroxy-4-methoxybenzaldehyde oxime (4-MeO-H2salox) and Mn(ClO4)2·6H 2O with 1,2-di(4-pyridyl)ethylene (dpe) in MeOH/DMF mixtures yields the one-dimensional complex {[Mn3O(4-MeOsalox)3(dpe) 1.5(DMF)2(H2O)](ClO4)}n (3·DMF·H2O). Complex 1·MeOH shows a typical structure of a [MnIII3O]7+ core, and complex 2 contains a dimer [MnIII3O]7+ core connected by a Na+ ion. Complex 3 has a one-dimensional chain structure constructed from [MnIII3O]7+ units linked by dpe ligands. Magnetic analysis shows that all three complexes exhibit antiferromagnetic interactions between the MnIII ions.
