WebAug 22, 2024 · Ligand substitution is characterized by a continuum of mechanisms bound by associative (A) and dissociative (D) extremes. At the associative extreme, the incoming ligand first forms a bond to the metal, then the departing ligand takes its lone pair and leaves. At the dissociative extreme, the order of events is opposite—the departing ligand ... WebI0 enantiomeric pairs (Pig. I), while for the trigonal twist it is decom- posed into two enantiomeric matrices (Pig. 2). Each of these describes pseudorotation of I0 isomers which cannot be interconverted to their enantiomers in the …

WebThe trigonal twist mechanism mechanism has rarely been demonstrated in octahedral complexes with monodentate ligands. The mechanism has been demonstrated for Ru(CO)H₂(PPh₃)₃. There is exchange between the two hydrides.
