WebApr 4, 2024 · A series of Pt(II) complexes containing a donor–π–acceptor (D–π–A) isomer ligand (ortho-, meta-, and para-position; Pt-O, Pt-M, and Pt-P) is prepared to investigate the positional isomerism on the Pt(II) complex. In particular, the metal-to-ligand charge transfer and ligand intramolecular charge transfer characteristics are examined ... Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical properties, except for the direction in which they rotate polarized light and how they interact with different opt…

Structural isomers atoms are bound in different orders while stereoisomers are bound in the same order but oriented differently. Geometric isomers involve different arrangement about a double bond.
