Write the `IUPAC` names for the following coordination compounds:
(i). `[Co(NH_3)_6]Cl_3`
(ii). `[Co(NH_3)_5Cl]Cl_2`
(iii). `K_2[Fe(CN)_6]`
(iv). `K_3[Fe(C_2O_4)_3]`
(v). `K_2[PdCl_4]`
(vi). `[Pt(NH_3)_2Cl(NH_2CH_3)]Cl`

Explanation

To write the IUPAC names for the given coordination compounds, we will follow a systematic approach. Here’s the step-by-step solution for each compound:

### Step-by-Step Solutions:

#### (i) `[Co(NH_3)_6]Cl_3`
1. Identify the central metal ion: Cobalt (Co).
2. Determine the ligands: There are six ammonia (NH₃) ligands.
3. Name the ligands: Since there are six ammonia ligands, it is called "hexaammine".
