Synthesis, characterization and crystal structures of Ni(II) and Cu(I) complexes with the condensation product of 2-(diphenylphosphino) benzaldehyde and 1-hydrazinophthalazine

A square-pyramidal Ni(II) complex (1) with the composition [NiL(HL')]CIO4 center dot H2O was synthesized in the reaction of nickel(II) perchlorate and 2[2-(diphenylphosphino)benzylidene]-1-phthalazinylhydrazone (HL). The coordination surrounding the Ni(II) ion consist of a PNN coordinated deprotonated HL ligand and its corresponding oxidation product phosphine oxide HL' coordinated via two nitrogen atoms of the hydrazinophthalazine moiety. The structure of Ni(II) complex 1 was determined by X-ray analysis, IR spectroscopy, elemental analysis and magnetic measurements. In the reaction of copper(II) perchlorate with HL, a binuclear phthalazine bridged Cu(I) complex (2) was obtained with the composition [Cu-2(HL)(2)](ClO4)(2)center dot C2H5OH. The structure of Cu(I) complex 2 was determined by X-ray analysis, IR and NMR spectroscopy, elethental analysis and magnetic measurements.Peer-reviewed manuscript: [http://cherry.chem.bg.ac.rs/handle/123456789/3256]Supplementary material: [http://cherry.chem.bg.ac.rs/handle/123456789/3257

Synthesis, structure, spectroscopic studies and magnetic properties of Cu2N2O4-, Cu2N2O2(S2)-, Cu2N2S4-chromophores based on aminomethylene derivatives of pyrazole-5-one(thione)

The aminomethylene derivatives of pyrazole-5-one (6) and pyrazole-5-thione (7) were synthesized in the reaction of 2-aminophenol (4) with corresponding 1-phenyl-3-methyl-5-X-pyrazole-4-carbaldehyde (1, X = hydroxy) or (2, X = sulfanyl). Reaction of 2-aminobenzenethiol (5) with 1-R-3-methyl-5-sulfanyl-pyrazole-4-carbaldehydes (2, R = phenyl and 3, R = isopropyl) results in the formation of disulfide compounds 8 and 9. The structures of compounds 6–9 were determined by IR and NMR spectroscopy and elemental analysis. The reaction of each ligand 6–9 with copper(II) acetate monohydrate in ethanol resulted in dinuclear metal-chelates with Cu2N2O4, Cu2N2O2S2, Cu2N2S4 chromophores. All complexes were characterized with C, H, N elemental analysis, FT-IR, ESR and X-ray absorption spectroscopy. The structures of the complexes 11 and 13 were determined by X-ray single-crystal diffraction. The variable-temperature magnetic susceptibility measurements in the 2–300 K temperature range were performed and the influence of the type of bridging atoms on the magnetic and spectral properties was discussed. The nature of magnetic and spectral properties of the copper chelates was analyzed using DFT quantum-chemical calculations within broken-symmetry and time dependent (TD DFT) approximations, correspondingly.Supplementary material: [https://cherry.chem.bg.ac.rs/handle/123456789/4236
