Doubt from Coordination Compounds

Both CO and P(ph)3 are strong ligands but there is an exception that in case of Ni coordination complexes, p(ph)3 acts as a weak ligand.
Both will be tetrahedral.

Thanks a lot!

Hi. Its Ni (PPh3)2cl2 can be both sq planar and tetrahedral.

Chemistry is not black and white. It depends on many factors.

My suggestion would be to consider those ligands where the donor atoms are C and N to be strong while others as weak.

This is not strictly true, but if your aim is to clear jee memorise this rule.

Yes, thanks!
