WebThe spectrochemical series is an empirically-derived list of ligands ordered by the size of the splitting Δ that they produce. It can be seen that the low-field ligands are all π-donors (such as I-), the high field ligands are π-acceptors, such as CN-and CO), and ligands such as H 2 O and NH 3, which are neither, are in the middle.

http://snst-hu.lzu.edu.cn/zhangyi/ndata/Ligand_field_theory.html WebCell-surface receptors are membrane-anchored proteins that bind to ligands on the outside surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands.

WebCrystal field theory. The crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of neutral molecules. WebLigand field theory was developed during the 1930s and 1940s as an extension of crystal field theory (CFT). CFT describes certain properties of coordination complexes but is …
