Chelating vs bridging
WebCoordination compounds containing polydentate ligands are called chelates (from Greek chele, “claw”), and their formation is termed chelation. Chelates are particularly stable and useful. An example of a typical chelate is bis (1,2-ethanediamine)copper (2+), the complex formed between the cupric ion (Cu 2+) and the organic compound ...

WebThe presence of relatively bulky substituents on N resulted in a higher chelating power of the ligands. The thermodynamic study of the equilibrium between the chelate and the bridged forms of clusters 9–11 showed that the bridged form is favoured by enthalpic factors whereas entropic factors favour chelation. WebIndeed, with such a linker, the mode of coordination (chelating vs bridging) depends on the conditions of complexation. Moreover, chelation would prevent reductive elimination between NHC and hydride only if it forced the imidazolyl ring to be planar to the coordination plane, and here the linker is too flexible.
