Give the IUPAC names of the following compound `[Cr(NH_3)_3(NO_2)_3]`

Explanation

To determine the IUPAC name of the coordination compound \([Cr(NH_3)_3(NO_2)_3]\), we will follow a systematic approach:

### Step 1: Identify the central metal atom and its oxidation state
- The central metal atom in this compound is chromium (Cr).
- To find the oxidation state of chromium, we can set up the equation based on the charges of the ligands:
- Let the oxidation state of chromium be \( x \).
- The amine ligand (\( NH_3 \)) is neutral, contributing 0 to the charge.
- The nitrito ligand (\( NO_2 \)) has a charge of -1 and there are three of them.
