title: Synthesis of a high-valent, four-coordinate manganese cubane cluster with a pendant Mn atom: photosystem II-inspired manganese-nitrogen clusters.
abstract: High-valent, four-coordinate manganese imido- and nitrido-bridged heterodicubane clusters have been prepared and characterized by single-crystal X-ray diffraction and spectroscopic techniques. The title compound, a corner-nitride-fused dicubane with the chemical formula [Mn(5)Li(3)(μ(6)-N)(N)(μ(3)-N(t)Bu)(6)(μ-N(t)Bu)(3)(N(t)Bu)] (1), has been prepared as an adduct with a nearly isostructural tetramanganese cluster with one Mn atom replaced by Li. An important feature of the reported chemistry is the formation of nitride from tert-butylamide, indicative of N-C bond cleavage facilitated by manganese.
