Manganese(IV) Complexes with Tridentate Diacidic Ligands. Crystal Structure of Acetyl-acetonato-salicylaldehydebenzoylhydrazonato(2-)-methanol-manganese(III)The manganese(IV) chelates of salicylaldehyde benzoylhydrazone and salicylaldehyde salicylhydrazone were synthesized by ligand exchange reactions using bis(acetylacetonato)manganese(II), tris(acetylacetonato)manganese(III) as well as manganese(III) acetate. The brown complexes show the expected molecular ions in the APCI mass spectra. As an intermediate compound acetyacetonato-salicylaldehydebenzoylhydrazonato(2-)-methanol-manganese(III) was isolated and characterized by X-ray structural analysis. Crystallographic data see “Inhaltsübersicht”.
Notes:
Durch Ligandenaustauschreaktion von Bis(acetylacetonato)mangan(II) und Tris(acetylacetonato)mangan(III) bzw. Mangan(III)-acetat mit Salicylaldehydbenzoylhydrazon und -salicylhydrazon wurden die Mangan(IV)-Chelate dieser Liganden dargestellt. Die braunen Verbindungen zeigen im APCI-positiv Massenspektrum die erwarteten Molekülionen. Für das Zwischenprodukt Acetylacetonato-salicylaldehydbenzoylhydrazonato(2-)-methanol-mangan(III) wurde die Kristall- und Molekülstruktur bestimmt: Gitterabmessungen bei 293 K; a = 754,3(2) pm, b = 1 027,3(6) pm, c = 1 357,4(5) pm, α = 79,64(4)°, β = 76,51(3)°, γ = 70,45(4)°, Raumgruppe P1 (Nr. 2), Z = 2, 3297 unabhängige Reflexe, R = 3,84%.
