Abstract
Nickel-based complexes are increasingly studied due to their promising roles in medicine, catalysis, and energy storage. This review offers an in-depth survey of recent progress in the synthesis of nickel complexes, with emphasis on methods involving both organic and inorganic ligands. The influence of ligand type on the stability, geometry, and electronic characteristics of these complexes is discussed in detail. Key analytical techniques, such as UV-Vis spectroscopy, FTIR, NMR, and X-ray diffraction, are highlighted for their importance in characterizing the structure and composition of nickel complexes. The review also examines the electrochemical properties of these compounds, focusing on their redox behavior and potential applications as catalysts in energy-related processes. Critical factors influencing the performance and reactivity of nickel complexes, including ligand environment, nickel oxidation state, and coordination geometry, are identified and analyzed. This article aims to provide valuable insights for researchers focusing on the design, characterization, and diverse applications of nickel-containing complexes in various scientific fields.
