“A COMPARATIVE STUDY OF COPPER(II) AND NICKEL(II) COMPLEXES”

Abstract

Many chemical and biological processes depend on coordination complexes made of transition and main group elements. Coordinate covalent bonds hold ligands to a central metal atom or ion in these complexes. The ligands can form chelates with tetrahedral, square planar, or octahedral geometries, depending on how many donor atoms they include. Also, some compounds display optical or cis-trans isomerism. Coordination compounds are very helpful in fields like oxygen transport, water purification and medicine because of these special qualities.
