Electrochemical Properties and Hirshfeld Analysis of an Octahedral Nickel Schiff Base Complex

This study reports the synthesis and characterization of a nickel complex. Its structure was determined to be octahedral, with the nickel ion coordinated by two cis nitrogen atoms and four oxygen atoms (two from the ligand, two from water molecules). Notably, the aliphatic OH of the ligand did not participate in coordination. Hirshfeld surface analysis was conducted to examine intermolecular interactions, the results confirmed the presence of π-π interactions related to planar stacking, the sum of results provide valuable insights into the crystal packing and structural stability of the complex.We have also investigated the electrochemical behavior of the ligand and the complex by cyclic voltammetry.
