A coordiantion compound has the formula `CoCl_(3).4NH_(3)`. It does not liberate `NH_(3)` but forms a precipitate with `AgNO_(3)` . Write the structure and IUPAC name of the complex compound. Does it show geometrical isomerism?

Explanation

To solve the problem step by step, we will analyze the coordination compound with the formula \( \text{CoCl}_3 \cdot 4\text{NH}_3 \).

### Step 1: Identify the Coordination Complex
The given formula indicates that cobalt (Co) is the central metal atom, surrounded by three chloride ions (Cl) and four ammonia molecules (NH3).

### Step 2: Determine the Oxidation State of Cobalt
To find the oxidation state of cobalt in this complex, we can set up the following equation:
