Abstract

The crystal and molecular structures of [Mn(phen)-(OH2)Cl3] (1) and [Mn(acac)2(OH2)2]ClO4·2H2O (2) were determined. A comparison is made of the Jahn-Teller distortion in these compounds with those observed in other manganese(III) complexes with monodentate axial ligands.

Abstract

The Ce4+ oxidation of Mn2+ in acetic acid in the presence of 2,2?-bipyridine gives the unsymmetrical complex [Mn2O(OAc)2(H2O)(NO3)(bpy) 2](ClO4) � CH3COOH. The crystal structure of the complex shows the coordination of both nitrate and water to the metal ion. Each metal centre exhibits Jahn-Teller distortion and results in two types of Mn - OOAc bonds. The formation of different high-valent manganese complexes by Ce4+ oxidation under different conditions is discussed in the light of possible disproportionation and proton-coupled electron transfer reactions. The mode of (pseudo) Jahn-Teller distortion seen in manganese(III,III) complexes having the Mn2O(OAc)2+ 2 core is reviewed. Copyright ? 1996 Elsevier Science Ltd.
