What is the coordination number of [Pt(NH3)4]2+
The coordination number of a complex is the number of ligands surrounding the central metal ion. To determine the coordination number of [Pt(NH3)4]2+, we need to count the number of ligands coordinated to the Pt (platinum) ion.
In this case, the complex is [Pt(NH3)4]2+. It contains four ammonia (NH3) ligands coordinated to the platinum ion. Each ammonia molecule contributes one ligand, so the coordination number is 4.
To determine the coordination number of a complex, you can look at the chemical formula and identify the ligands coordinated to the central metal ion. Counting the number of ligands will give you the coordination number.
