Is sulphate a weak ligand?

First and hopefully obvious things first: sulphate ions do form (weak) coordinate bonds to metal centres and thus by definition cause some d orbital splitting.

How do you know if a ligand is strong or weak?

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

What type of ligand are so42?

Which ligand are very strong ligand?

Spectrochemical series of ligands (For a table, see the ligand page.) Ligands arranged on the left end of this spectrochemical series are generally regarded as weaker ligands and cannot cause forcible pairing of electrons within the 3d level, and thus form outer orbital octahedral complexes that are high spin.

Is sulphate a ligand?

The sulfate ion can act as a ligand attaching either by one oxygen (monodentate) or by two oxygens as either a chelate or a bridge. An example is the complex [Co(en)2(SO4)]+Br− or the neutral metal complex PtSO4(P(C6H5)3)2 where the sulfate ion is acting as a bidentate ligand.

Is oxalate a strong or weak field ligand?

OX²- or C2O4²- or oxalate is a weak field ligand. The answer is no. OX²- or C2O4²- or oxalate is a weak field ligand.

Is oxalate a strong ligand?

Actually oxalate is intermediate field ligand i.e it can behave as both weak as well as strong field ligand. In all cases except [Co(ox)3]3- it behaves as weak field ligand. Here [Co(ox)3]3- it behaves as strong field ligand, this is only one rare example where it is strong field ligand.

What are strong and weak field ligands give example?

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. Weak field ligands contain halogen, O, and S as donor atoms. e.g. F– , Cl– , Br– , I–, SCN–, C O C 2 O 4 2 – .

Is sulfate a ligand?

Is sulphate monodentate ligand?

Coordination Compounds. Give one example of each complex in which sulphate ion acts as mondenate and bidentate ligand. [Co(NH3)5SO4]Br: In penta amine sulphato cobalt(lll) bromide, SO42– ion is acting as monodenate ligand.

What is difference between sulphate and sulfate?

“Sulfate” is the spelling recommended by IUPAC, but “sulphate” was traditionally used in British English.
