One-pot synthesis, crystal structure and theoretical calculations of a dinuclear Mn(III) complex with in-situ generated O,N,O- and O,N-donor dichelating hydrazone ligand

A new dinuclear Mn(III) complex, [Mn2(L)2(CH3OH)2] (1), was synthesized by one-pot reaction of 2-aminobenzoylhydrazide, salicylaldehyde and Mn(OAc)2·4H2O in methanol (H3L = (E)-N'-(2-hydroxybenzylidene)-2-((E)-(2-hydroxybenzylidene)amino)benzohydrazide). The obtained compound was characterized by elemental analysis, spectroscopic methods, thermogravimetric analysis (TGA) and single crystal X-ray studies. Structural studies indicated that a...
