摘要：

The new hexadentate, bis-pincer ligand, (dipyCH(2))MeNCH2CH2NMe(CH(2)dipy) (dipy = 2,2'-dipyridyl-6-yl) forms a crystallographically characterized Mn(II) complex in which each half of the ligand binds a separate Mn(OAc)(2) unit. The structure consists of a distorted N3Mn(eta(2)-OAc)(eta(1)-OAc) core with six normal coordinate bonds and a long (2.85 angstrom) secondary bond to a seventh ligand atom, an oxygen of the ill-acetate. In addition to demonstrating an interesting coordination mode, the structure also mimics a predicted transition state in the associative ligand exchange of octahedral Mn(II) complexes.
