Valence Tautomerism in ao-Benzoquinone Adduct of a Tetraazamacrocycle Complex of Manganese
摘要:
Two different charge distributions of the complex cation [MnIII (cth)(diox)]+ (cth=a tetraazamacrocycle, diox=3,5-di-tert-butyl-o-benzoquinone; structure shown in the picture) can be isolated by varying the counteranion: [MnIII (cth)(cat)]BPh4 and [MnII (cth)(sq)]ClO4 (cat and sq denote the catecholato and semiquinonato forms of the ligand). The complex undergoes noncooperative entropy-driven valence tautomeric transitions.
