Zusammenfassung:[Cr super(III) sub(8)M super(II) sub(6)] super(12+) (M super(II)=Cu, Co) coordination cubes were constructed from a simple [Cr super(III)L sub(3)] metalloligand and a "naked" M super(II) salt. The flexibility in the design proffers the potential to tune the physical properties, as all the constituent parts of the cage can be changed without structural alteration. Computational techniques (known in theoretical nuclear physics as statistical spectroscopy) in tandem with EPR spectroscopy are used to interpret the magnetic behavior. All about cubes: [Cr super(III) sub(8)M super(II) sub(6)] super(12+) (M=Cu, Co) cubes were constructed from a simple [Cr super(III)L sub(3)] metalloligand and a "naked" M super(II) salt. The flexibility in the design proffers the potential to tune the physical properties, as all the constituent parts of the cage can be changed without structural alteration. Statistical and EPR spectroscopy were used to interpret the magnetic behavior.
