Synthesis, Spectroscopic and Thermal Investigations of O‐Phd and P‐Phd Bridged Binuclear Manganese (III) Schiff Base Complexes Derived from Pyrazolone Base Ligands

摘要: Acyl pyrazolone and their derivatives are an important class of chelating compounds called heterocyclic β‐diketones. β‐diketones have played, continue to play, a key role in coordination that found wide application several fields, from new materials catalysts, as precursors for CVD the microelectronic industry potential antitumourals. Due variety this ligand, there studies on metal complexes many researchers, including ours. We herein report structural variability moiety its nature with manganese (III) ions, mononuclear binuclear complexes. The complex [Mn(PMFP)(bipy)(OAc)]ClO4 [Mn(PMFP‐Me) (bipy)(OAc)]ClO4 was prepped by reaction Mn(OAc)3 · 2H2O ligand PMFP or PMFP‐Me (where PMFP=5‐Hydroxy‐3‐methyl‐1‐phenyl‐1H‐pyrazole‐4‐carbaldehyde; PMFP‐Me=5‐hydroxy‐3‐methyl‐1‐p‐tolyl‐1H‐pyrazole‐4‐carbaldehyde; bipy=2,2′bipyridyl). corresponding were prepared b...
