Co-ordination number of Pt in [PtCI(NO): (NH3)2] is ______?
Co-ordination number of Pt in [PtCI(NO): (NH3)2] is ______?
Explanation
The coordination number of a metal atom in a complex is the number of ligands directly attached to it.
In [PtCl(NO)(NH₃)₂], the ligands are:
- Cl⁻ (1)
- NO (1)
- NH₃ (2)
Total number of ligands = 1 + 1 + 2 = 4
The coordination number of Pt is 4, since it is bonded to 4 ligands.
