Ligand steric properties

Evaluation of anti-inflammatory and antioxidant activities of Copper (II) Schiff mono-base and Copper(II) Schiff base coordination compounds of dien with heterocyclic aldehydes and 2-amino-5-methyl-thiazole

“…thiazoline and its derivatives [12 -13]. The bioactivity of S, N-thiazoles is largely due to their structural similarities with the imidazolyl entities of proteins [19], as well as biological features [20][21] Their participation in the formation of compounds can modify [20 -29] the bioactive and pharmaceutical characteristics of the adducts. Among the thiazoles employed to date, the 2-amino-5-methylthiazole is most appropriate for the enhancement of the bioactivity of already synthesized compounds.…”

Electrochemical behaviour and structure of novel phosphine- and phosphite-substituted tungsten(0) Fischer carbene complexes

“…The σ-donor, π-acceptor [8] and steric [9] characteristics of phosphines can be regulated by modification of their substituents. Phosphines have many applications in organometallic chemistry, specifically as ligands in homogenous catalysts [10].…”

Molecular mechanics-based measures of steric effects: Customized code to compute Ligand repulsive energies

“…6,7 In a chemical reaction involving a ligand with many conformational degrees of freedom, there is always an ensemble of conformers of the ligand in solution. However, most measures of steric size only take into account one conformation of the ligand.…”

“…Many of these values are updated from those that appear in the literature. 4,6,7,12,13 ERCODE can be used to calculate steric sizes of any ligand in any prototypical environment as long as a representative structure is found, the file converted into a bgf type, and appropriate van der Waals parameters are defined.…”
