Strategy:
 Use the stoichiometry of precipitation to determine the number of ionizable chloride ions, which then allows deducing the coordination sphere composition and the denticity of the unknown ligand L.

Step 1: Analyze precipitation data
- 1 mol of complex gives 1 mol of .
This indicates only 1  is ionizable (outside the coordination sphere).

Step 2: Determine inside coordination sphere
The formula is .
If 1 Cl is outside, then 2 Cl must be inside the coordination sphere.

Step 3: Determi
