WebSome ligands are 'weak' but will form strong ligand fields with certain metals in certain oxidation states. Co 2+ will behave more like other metals on the table and form a high spin complex with oxalate. (C2O4)2- is a weak field ligand but due to chelation it behave as strong field ligand. It's not because of chelation effect. Web5 de mai. de 2024 · May 4, 2024 at 17:36. 1.

WebCyanide ion is a strong ligand. It will cause greater splitting between the respective orbitals. In case of strong ligands, pairing of electrons will be higher. Therefore, they are low-spin complexes. Therefore, strong field ligands such as cyanide produce low spin complexes and high field splitting. Therefore, the correct option is (c). WebTransition metal complexes can exist as high spin or low spin depending on the strength of the ligands.Let's understand how the strength of ligands affect th... WebAnswer (1 of 5): For solving such questions the following problem solving strategy can be used in the given sequence: 1. Check the number of weak and strong field ligands, whichever are more will determine the outcome e.g. [Fe(H2O)2(CN)3(NH3)] is a low spin complex because of majority SFLs. 2.
