The coordination number of a central metal atom in a complex is determined by

Option: 1

the number of ligands around a metal ion bonded by sigma bonds


Option: 2

the number of ligands around a metal ion bonded by pi-­bonds


Option: 3

the number of ligands around a metal ion bonded by sigma and pi-­bonds both


Option: 4

the number of only anionic ligands bonded to the metal ion.

As we have learnt, 

Coordination number is the number of ligands which are bonded directly to metal by co-ordinate bonds.

Thus, co-ordination number is the number of ligands around a metal atom/ion bonded by sigma bonds

Therefore, option (1) is correct.
