Symmetry and Topology Determine the Mo~V-CN-Mn~(II)Exchange Interactions in High-Spin Molecules

摘要

The two conditions that the ground state of a compound must meet in order to behave as a single-molecule magnet'are a high spin and a significant anisotropy(i.e.a large uniaxial zero-field-splitting parameter).It is not surprising,therefore,that an increasing number of polynuclear transition-metal compounds are currently being reported in which the individual spins of the metal atoms are coupled through exchange interactions in such a way so as to produce a high total molecular spin.
