Organometallic optical isomers
Witryna1 mar 2024 · Geometric isomers are chemical species with the same type and quantity of atoms as one another, yet having different geometric structures. In geometric … WitrynaIn this article, we describe a series of complex salts in which electron-rich {FeII(CN)5}3- centers are coordinated to pyridyl ligands with electron-accepting N-methyl/aryl-pyridinium substituents. These compounds have been characterized by using various techniques including electronic absorption spectroscopy and cyclic voltammetry. …
