Does ligand exchange change complex shape

WebJul 23, 2015 · However, $\ce{Cu^{+2}}$ ions usually adopt a distorted octahedral geometry, with two ligands having a longer bond length than the four others. These two are very weakly bound and exchange quickly. For this reason the $\ce{NH3}$ complex is written with only four molecules; the two other are so weakly bound. WebLigand exchange (or ligand substitution) is when one ligand in a complex is replaced by another. Ligand exchange forms a new complex that is more stable than the original one. The ligands in the original complex can be partially or entirely substituted by others. There are no changes in coordination number, or the geometry of the complex, if ...
