Abstract

Bridging-azido ligands are used to create a new dodecanuclear manganese cluster [Mn12O4(salox)12(N3) 4(MeOH)6(H2O)2] ·5MeOH·2H2O (1·5MeOH·2H2O) from the arrangement of manganese triangles, [Mn3O]. Single-crystal x-ray analysis shows that 1·5MeOH·2H2O contains a [MnIII123-O)42- N3)4]24+ core, constructed from four [Mn III3O]7+ building units, which is a new structural type in the family of Mn12 complexes. Variable temperature magnetic susceptibility and magnetization measurements of the complex 1·5MeOH·2H2O were carried out. The magnetic data indicate that complex 1·5MeOH·2H2O exhibits antiferromagnetic with a non-zero ground state spin value of S = 4. The frequency dependence of out-of-phase component in alternating current magnetic susceptibility and magnetic hysteresis loop measurements indicate that complex 1·5MeOH·2H2O is a new single-molecule magnet with a significant magnetoanisotropy of Ueff = 70 K.
