Crystal structure, optical properties, DFT analysis of new morpholine based Schiff base ligands and their copper(II) complexes: DNA, protein docking analyses, antibacterial study and anticancer evaluation

New morpholine derived Schiff base ligands (HL1 and HL2) and their Cu(II) complexes [Cu(L1)2] (1) and [Cu(L2)2] (2) have been synthesized and characterized by 1H NMR, IR, UV–Vis, EPR studies and cyclic voltammetric analyses. Single crystal X-ray crystallography studies confirm the structure of newly synthesized Schiff base ligands HL1 and HL2. The ground state electronic structures of Cu(II) complexes 1 and 2 have been investigated by DFT/B3LYP...
