A square pyramidal copper(II) complex of a Schiff base ligand: synthesis, crystal structure, antibacterial and DNA interaction studies

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

“…This shifting of the imine stretching frequency value to lower wavenumber in complex 1 was due to the donation of lone-pair electrons from ligand imine nitrogen atom to the vacant d-orbital of the Cu(II) ion. 3,13,75,93 The Cu 2+ -bound phenoxido oxygen stretching frequency n (Cu-O/ring stretch) appeared as a weak peak at 861 cm À1 . 94 Electronic spectra of ligand H 2 L and complex 1 displayed several representative bands in the 200-800 nm range in MeCN solution.…”

“…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][2][3][4][5][6][7][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, proteins and the role of catechol oxidases is to catalyze the oxidation of catechols to orthoquinones in the presence of air.…”

Chromophore appended DPA-based copper(ii) complexes with a diimine motif towards DNA binding and fragmentation studies

“…The reduction peak at −0.30 V is because of copper deposition at the working electrode surface. 48,49 The cyclic voltammogram of L2 showed irreversible oxidation peaks at 1.32 V and 1.58 V (Fig. S21 †).…”

“…Similarly, the reduction peak at −0.28 V is due to copper deposition at the electrode surface. 48,49 The reduction peaks at −1.54 V and −1.51 V in 1 and 2, respectively, could be assigned to bpy-based reduction (Table 3). 50…”

Practical and Computational Studies of Bivalence Metal Complexes of Sulfaclozine and Biological Studies

“…The octahedral arrangements were observed in three metal ions, Ni(II), Fe(II), and Co(II), binding to Cl ions, compatible with the conductance results. The Zn(II) complex showed a tetrahedral geometry, which is one of the passable possible structures for an ion metal (Dudev and Lim, 2000;Jana et al, 2017). There were many attempts to get single crystals from the metal complexes using the diffusion method with DMS and chloroform or ethanol and benzene but all failed.…”
