In coordination compounds when the the weak field ligands acts as strong ligands ...and what are they?

Saniya Khatri 25th Mar, 2026

Hi,

Weak field ligands like $H_2O$, $F^-$, and $Cl^-$ can act as strong ligands when bound to small, highly charged metal ions (e.g., $Cr^{3+}$, $Co^{3+}$, $Pt^{4+}$) or in environments that enhance orbital overlap. Ligand strength depends on the metal ion and bonding conditions.
