The coordination number of central metal atom in a complex is determined by
Options
- Athe number of ligands around a metal ion bonded by sigma bonds
- Bthe number of ligands around a metal ion bonded by bonds
- Cthe number of ligands around a metal ion bonded by sigma and bonds both
- DNone of the above
Correct answer
A. the number of ligands around a metal ion bonded by sigma bonds
Step-by-step solution
The number of atoms of the ligands that are directly bound to the central metal atom or ion by coordinate bond is known as the coordination number of the metal atom or ion. Coordination number of metal = number of bonds formed by metal with ligands.
