Syntheses, crystal structures, antibacterial activities and non-linear optical properties based on DFT calculation of two substituted benzyl piperidinium salts tetrahalogenated copper(II)

Preparation, crystal structure, optical properties, Hirshfeld surface analysis and antimicrobial activity of 4-nitrobenzyl-4-aminopyridinium tetrachlorocuprate(II)

“…The bands at 3378 cm − 1 and 3309 cm − 1 are caused by the asymmetric stretching vibration of amino groups (ν as NH 2 ) and the symmetric stretching vibration (ν s NH 2 ) [48]. The absorption band at 3201 cm − 1 is attributed to N-H stretching vibration of the pyridine ring, and the band at 3056 cm − 1 is attributed to C-H stretching vibrations on pyridine rings [49]. The absorption band near 1650 cm − 1 and 1594 cm − 1 dues the C = C stretching vibration of benzene rings and the C = C stretching vibration of pyridine rings [50].…”

Investigations on a mononuclear Cu(ii) Schiff base complex: theoretical calculations, catechol oxidase activity, and protein binding interaction analysis

“…Transition metal complexes with Schiff base ligands have received noteworthy interest from the scientific fraternity in the last few decades owing to their fascinating structural topology, magnetism, and catalytic and biological activity. 1–8 Schiff bases have gained great importance due to their wide range of applications, such as anticancer, 9,10 anti-inflammatory, 11,12 antimicrobial, 1,13,14 antioxidant, 15,16 photophysical, 17,18 optical, 19,20 catalytic 21,22 and electrochemical properties. 23,24 Among all the inorganic transition metal ions copper( ii )-containing compounds with an advanced mode of design have been explored for various catalytic activities, protein–complex binding studies, DNA binding and cleavage activities, 25–27 and antimicrobial activities.…”
