Abstract

A new cage cobalt(II) complex exhibiting a single-molecule magnet behavior has been synthesized by a template reaction on a metal ion as a matrix. The complex was characterized by elemental analysis and NMR spectroscopy. The magnetic properties have been studied by ac and dc magnetometry. The data obtained made it possible to determine the relaxation characteristics of this single-molecule magnet and compare them with those for a series of analogous recently reported cage cobalt(II) complexes.
