“…The crystal structures of 1, 2a and 3a reveal that the hydrazone ligand is attached to the rhenium(I) center through the N py -N bidentate chelating system. Although the literature reports that the studied hydrazones coordinate to different metals through the tridentate N py -N-O system, 5,15,36,37 the facial arrangement of the [Re(CO) 3 ] + core prevents tridentate coordination, as observed in the crystal and molecular structures of other tricarbonylrhenium(I) complexes with related hydrazones. 30,31,33 Hence, the Re atom of each compound (1, 2a and 3a) is coordinated to three CO groups, one chlorine atom and two nitrogen atoms of the hydrazone ligand while the carbonyl oxygen does not bind to the metal.…”

“…The theoretical results are following the experimental infrared spectroscopic data, showing the coordination of the hydrazone HL in anionic mode through the NNO chelating system, as observed in copper(II) complexes with 2‐acetylpyridine‐derived ligands. [ 45,81,93,94 ]…”

“…Considering the antimicrobial potential of metal complexes based on 2‐acetylpyridinebenzoylhydrazone (HL) ligand, [ 44–47 ] a new binuclear copper(II) complex was synthesized and characterized by elemental analysis, spectroscopic techniques, single‐crystal X‐ray diffraction, DFT, and molecular docking studies. The antibacterial and antifungal activity of the copper(II) complexes were tested in vitro against fungi and Gram‐positive and Gram‐negative bacteria.…”

“…Hydrazones readily form stable complexes with transition metals (Singh et al, 2013 ;Saif, et al, 2016), lanthanides (Ajlouni, et al, 2016), as well as main group elements (Pilóa et al, 2015). They form a wide variety of complexes with chemical, structural, biological and industrial importance.…”
