In optical isomerism, the two isomers are non superimposable mirror images of each other. In transition metal complexes this occurs when there are two or more bidentate ligands in a complex. halle jva

WebOct 15, 2024 · The three geometric isomers of [M(A-B-A) 2] complexes are mer, trans-fac, and cis-fac (Fig. 2), in some publications also denoted as mer (meridional), s-fac (symmetrical-facial), and u-fac (unsymmetrical-facial), respectively [22].The isomers can be classified according to their A1-M-A1′ (A2-M-A2′) and B1-M-B2 angles. Values of A1-M-A1′ … WebIn contrast, the analogous ruthenium(II) complexes of these ligands exist as a 1:1 mixture of the mer and fac isomers in solution [74,75]. 1 H-NMR spectroscopy was employed to further examine this behavior. halle jeans
