The new hexadentate, bis-pincer ligand, (dipyCH2)MeNCH2CH2NMe(CH2dipy) (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(η2-OAc)(η1-OAc) core with six normal coordinate bonds and a long (2.85 Å) secondary bond to a seventh ligand atom, an oxygen of the η1-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.
The crystal structure of a novel pseudo-seven-coordinate Mn(II) complex containing a long secondary bond to the seventh ligand atom demonstrates an interesting coordination mode, and mimics a previously predicted transition state in the associative ligand exchange of octahedral Mn(II) complexes.Figure optionsDownload as PowerPoint slide
