Effects of changing ions on the crystal design, non-covalent interactions, antimicrobial activity, and molecular docking of Cu(II) complexes with a pyridoxal-hydrazone ligand.

ABSTRACT: The present work reports the influence of the presence of different ions (Cl^-, Br^-, NO₃ ^-, or SO₄ ^2-) on the formation and proprieties of Cu(II) complexes with pyridoxal-benzoylhydrazone (PLBHZ). Four new complexes were successfully synthesized, [CuCl₂(PLBHZ)] (1), [CuBr₂(PLBHZ)] (2), [CuCl(PLBHZ)H₂O]⋅NO₃⋅H₂O (3), and [CuSO₄(PLBHZ)H₂O]⋅3H₂O (4), and characterized by spectroscopic and physicochemical methods. A single-crystal X-ray study reveals the Schiff base coordinated to the metal center tridentate by the ONS-donor system, resulting in distorted square pyramidal coordination geometries. Noncovalent interactions were investigate
