Abstract:
A series of novel dioxolene cobalt complexes with general formula (N-N)Co(3,6-diox)2 (where N-N = 2,2′-dipyridine (bpy) and 1,10-phenanthroline (phen), diox – mono- and dianionic forms of 3,6-di-isopropyl-o-benzoquinone (3,6-iPr-Q) and 3,6-di-cyclohexyl-o-benzoquinone (3,6-cHex-Q)) has been synthesized and characterized. The molecular structures of dipyridine adducts have been established by single crystal X-Ray structural analysis. Magnetic susceptibility measurements detect solid-state valence-tautomeric transformation occurring for complexes (phen)Co(3,6-iPr-SQ)2 and (bpy)Co(3,6-cHex-SQ)2. The phase transitions that accompany valence tautomeric transformation have been investigated by differential scanning calorimetry (DSC).
