What are strong field and weak field ligands?

Ligands that produce a large splitting are called strong field ligands, and those that produce a small splitting are called weak field ligands.

What is difference between strong ligand and weak ligand?

Strong Ligand vs Weak Ligand A strong ligand or a strong field ligand is a ligand that can result in a higher crystal field splitting. A weak ligand or a weak field ligand is a ligand that can result in a lower crystal field splitting.

How can you tell if a ligand is strong or weak?

Being lewis bases(those who donate electrons) the ligands with less electronegativity will be stronger. Therefore, in general halogen or oxygen donors (eg-F-,Cl-,Br-,H2O) are weak field ligands and the ones in which carbon or nitrogen atom is the donor (eg-CN-,CO,NH3) are strong field ligands.

What is the meaning of weak field ligand?

Definition of weak field ligand. A Ligand that exerts a weak crystal or ligand field and ge- nerally forms high spin complexes with metals. Search the Dictionary for More Terms.

Is Glycinate a strong field ligand?

Glycine is a weak field ligand as it contains both oxygen and nitrogen atom.

What is a strong ligand?

– A strong ligand or a strong field ligand is any ligand which has high crystal field theory. – The complexes formed in this are called low spin complexes. – They are mostly diamagnetic or less paramagnetic than weak fields.

What is strong ligand?

i. Strong field ligands: Those ligands which cause larger splitting of d orbitals and favour pairing of electrons are called strong field ligands. Strong field ligands contain C, N, and P as donor atoms. e.g. CN– , NCS– , CO, NH3, EDTA, en (ethylenediammine). Weak field ligands contain halogen, O, and S as donor atoms.

Which is not strong field ligand?

In easy words we can say that ligands in which donor atoms are oxygen, sulphur and halogens are weak field ligands. On other hand ligands in which donor atoms are carbon, phosphorus and sulphur are known to be strong field ligands.
