The synthesis and characterization of a new unsymmetrical dinucleating N,O-donor ligand, 2-[N,N-bis(2-pyridylmethyl)aminomethyl]-6-[N-(3,5-di-tert-butyl-2-oxidobenzyl)-N-(2-pyridylamino)aminomethyl]-4-methylphenol (H(2)Ldtb), as well as the X-ray crystal structure of its corresponding mixed-valence diacetate-bridged manganese complex, di-mu-acetato-mu-2-[ N,N- bis(2-pyridylmethyl)aminomethyl]-6-[ N-(3,5-di-tert-butyl-2-oxidobenzyl)-N-(2-pyridylamino)aminomethyl]-4-methyl-phenolato}dimanganese(II,III) tetraphenylborate, [Mn-II-Mn-III(C42H49N5O2)(C2H3O2)(2)](C24H20B), are reported. The complex may be regarded as an interesting structural model for the mixed-valence Mn-II-Mn-III state of manganese catalase.
