How do you know if a ligand is strong or weak? [FAQs!]

WebThese have simple and very well-defined structures. For example, their structures are usually tetrahedral, octahedral etc. In a metal carbonyl, the metal-carbon bond has the characteristics of both σ and π bonds. The bond between the carbonyl molecule and the metal becomes stronger by the synergic effect that the metal-ligand bond produces. WebApr 1, 2014 · One of the active sites is a Brønsted acid resulting from a hydroxo ligand that is produced by the elimination of hydrogen halide from the halogen and aqua ligands. The other active site is a coordinatively unsaturated metal, which can be isoelectronic with the platinum group metals by taking two or more electrons from the halogen ligands.
