摘要：

A monomeric manganese(II) catecholato complex with hydrotris(3-tert-butyl-5-isopropyl-1-pyrazolyl)borate (Tp(tBu,iPr)) was synthesized and characterized. X-ray analysis of the compound shows a tetrahedral manganese coordinated to one oxygen atom of the catecholato ligand and three nitrogen atoms of the Tp(tBu,iPr) ligand. The Mn-O distance (1.952(5) angstrom) is longer than the corresponding Fe-O distance (1.874(7) angstrom) in the analogous iron(II) Tp(tBu,iPr) complex due to the weaker Lewis acidity of manganese(II). Upon reacting of the manganese(II) complex with molecular oxygen, a manganese(II) semiquinonato complex was obtained, thus serving as an important model for catechol dioxygenase. This differs from the reaction of the iron(II) analog, which generates an iron(III) catecholato complex.
