Ligand orientation effects on metal–metal, ligand–ligand and metal–ligand interactions
Coordination Chemistry Reviews, 1999Abstract A number of chemical and physical properties of transition metal complexes can be explained by fundamental chemical criteria such as bond order, electron configuration, ligand or metal electronegativity, or the idealized coordination polyhedron. However, variations in the properties of similar compounds are associated with subtle differences

Ligand Design in Ligand‐Protected Gold Nanoclusters
Small, 2021AbstractThe design of surface ligands is crucial for ligand‐protected gold nanoclusters (Au NCs). Besides providing good protection for Au NCs, the surface ligands also play the following two important roles: i) as the outermost layer of Au NCs, the ligands will directly interact with the exterior environment (e.g., solvents, molecules and cells ...

The understanding of the pharmacology surrounding the cannabinergic system has seen many advances since the discovery of the CB1 receptor in the mammalian brain and the CB2 receptor in the periphery. Among these advances is the discovery of the endogenous ligands arachidonoylethanolamide (anandamide) and 2-arachidonoylglycerol amide (2-AG), which are ...

The adsorption of small molecules on the metal center of 3d metal phthalocyanines alters the bonding scheme of the molecule and can induce different spin states and magnetic moments, as well as trigger more exotic effects like Kondo resonance. Soft X-ray spectroscopy studies and computational studies have highlighted this kind of effects in magnetic ...

RANK ligand (RANKL), a key mediator of bone resorption in normal and pathological states, is expressed as membrane-bound or soluble forms by tissues as diverse as lymph nodes, spleen, thymus and bone-forming cells. In normal bone turnover and in bone metastasis, RANKL stimulates the formation and activity of bone-removing cells, osteoclasts, by binding

The selectins and their ligands
Current Opinion in Cell Biology, 1994The selectins are a family of carbohydrate-binding proteins, or lectins, that have stimulated tremendous interest because of their involvement in a wide array of interactions between leukocytes and endothelial cells. Highlights of recent progress include an extension of the list of instances of selectin participation in inflammatory diseases, further ...

Intramolecular ligandligand interactions in mixed ligand complexes
Inorganica Chimica Acta, 1983Abstract One of the most important properties of mixed ligand complexes is direct and metal ion-mediated ligandligand interactions, the latter being known as π-acidπ-base interactions around the central metal ion. Examples of direct intramolecular ligandligand interactions are ionic and hydrogen bonds between charged and/or polar side groups and ...

Intramolecular ligand-ligand interactions in mixed ligand complexes
Journal of Molecular Catalysis, 1984Abstract Intramolecular ligand-ligand interactions in the ternary Cu(II)- and Pd(II)- amino acid systems have been investigated by synthetic, spectroscopic and potentiometric methods. Various ternary Cu(II)- and Pd(II)- complexes containing amino acids with charged and/or polar side groups were isolated as crystals. Electrostatic interactions between
