Znligand
Znligand is a term used in coordination chemistry and bioinorganic chemistry to describe ligands that bind to zinc ions (Zn2+). Ligands in this context donate electron pairs from atoms such as nitrogen, oxygen, or sulfur and form coordination complexes with zinc. Zn2+ is a d10 metal ion that commonly adopts coordination numbers of 4 to 6, with geometries ranging from tetrahedral to distorted octahedral depending on the ligand set.
In synthetic and analytical chemistry, Znligands include water, hydroxide, halides, amines, carboxylates, phosphates, thioethers, and multidentate
In biology, Znligands are the side chains of amino acids that coordinate zinc within proteins. Commonly, cysteine
Analytical tools for studying Znligands include stability constants (log K), pZn values, X-ray crystallography, and spectroscopic
