why cyanide ions are not considered as ambidentated ligand though it can act as an isocyadide ion?

Expert Answer:

Ambidentated ligand: Ligands those have two different donor atoms
For example NO2, SCN, CN
[Cu(CN)4 ]3-  In this coordination compound, CN is the ligand, CN can be attached to central metal atom i.e. Cu through C (Cu → CN) and through N (Cu→ NC)
 This is possible because here, in this case, the transfer of charge is possible, the -ve charge can move between C and N.
