Reactions of MnX2 meltsalt (X = Cl and ClO4) and a quinquedentate Schiff base ligand together with its coligand azides in MeOH produced the unprecedented assembly of novel octa- and hexadecanuclear manganese clusters containing two and four alternant tetrahedral MnIII3MnII cores bridged by Schiff base ligands and versatile azides groups. The magnetic measurements on both compounds indicate dominant antiferromagnetic interactions between the metal centers. This synthetic approach may suggest a promising pathway to the design of novel Schiff base-based polynuclear manganese clusters and novel magnetic materials.
