Mixed carboxylate-bridged dimanganese(II/III) compounds prepared by an O2-dependent oxidative cleavage of ketones.

The structure of an O(2)-sensitive Mn(II)-Mn(II) complex with an unsymmetrical perchlorate bridge is reported. This complex promotes an O(2)-dependent oxidative cleavage of ketones giving mixed carboxylate complexes.

A dihydroxo-bridged Fe(II)-Fe(III) complex: a new member of the diiron diamond core family.

The first structurally characterized Fe(II)-Fe(III) complex containing a M2(mu-OH)2 diamond core is a Robin and Day class II mixed-valence complex.
