【 摘 要 】

The complexes bis(acetylacetonato-κ2O,O′)(N,N,N′,N′-tetramethylethylenediamine-κ2N,N′)manganese(II), [Mn(C5H7O2)2(C6H16N2)], bis(acetylacetonato-κ2O,O′)(N,N,N′,N′-tetramethylethylenediamine-κ2N,N′)iron(II), [Fe(C5H7O2)2(C6H16N2)], and bis(acetylacetonato-κ2O,O′)(N,N,N′,N′-tetramethylethylenediamine-κ2N,N′)zinc(II), [Zn(C5H7O2)2(C6H16N2)], were synthesized from the reaction of the corresponding metal acetylacetonates [M(acac)2(H2O)2] with N,N,N′,N′-tetramethylethylenediamine (TMEDA) in toluene. Each of the complexes displays a central metal atom which is nearly octahedrally surrounded by two chelating acac and one chelating TMEDA ligand, resulting in an N2O4 coordination set. Despite the chemical similarity of the complex units, the packing patterns for compounds 1–3 are different and thus the crystal structures are not isotypic.
