AB  - The Schiff base (HLBr), containing a chelating unit and triphenylphosphonium moiety has been synthesized in the reaction of 4-aminobenzyl(triphenyl)phosphonium bromide with 5-hydroxy-3-methyl-1-phenyl-4-formylpyrazole. The composition and structure of HLBr have been determined by elemental analysis, IR, 1D and 2D NMR, electronic spectroscopy and mass spectrometry. Density functional theory (DFT) calculations (6-311G(d,p) level of theory) have been carried out to investigate tautomeric forms of HL+ and the reaction mechanism of its formation and spectral properties. The most stable form in the solid state and in DMSO solution is pyrazolone (keto-amine) tautomeric form. [GRAPHICS] .

AB  - 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.

AB  - This study presents the synthesis, characterization and antimicrobial activity evaluation of beta-aminovinylphosphonium salts derived from aromatic amino acids. The compounds were prepared in the reaction of (formylmethyl) triphenylphosphonium chloride with various aromatic amino acids and their structures were determined by elemental analysis, IR and NMR spectroscopy. All synthesized compounds were tested for their antibacterial and antifungal activity.
