Novel tetranulear cobalt(II)-cobalt(III) mixed-valence complexes with a significant difference in magnetism
Tetranuclear cobalt(II)-cobalt(III) mixed-valence complexes with bis(benzoylacetone)-1,3-diiminopropan-2-ol (H3L), [Co4L2(C2H5O)(4)].CH3CN and [Co4L2(CH3O)(4)].2CH(2)Cl(2), have been synthesized and characterized by X-ray crystallography and magnetic susceptibility measurement.
