摘要：
Two different charge distributions of the complex cation [Mn(III)(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: [Mn(III)(cth)(cat)]BPh4 and [Mn(II)(cth)(sq)]ClO4 (cat and sq denote the catecholato and semiquinonato forms of the ligand). The complex undergoes noncooperative entropy-driven valence tautomeric transitions.
