Write the IUPAC names of the following coordiantion compounds:
(i) `[Co(NH_(3))_(6)]Cl_(3)`
(ii) `[Co(NH_(3))_(5)Cl]Cl_(2)`
(iii) `K_(3)[Fe(CN)_(6)]`
(iv) `K_(3)[Fe(C_(2)O_(4))_(3)]`
(v) `K_(2)[Pd Cl_(4)]`
(vi) `[Pt(NH_(3))_(2)Cl(NH_(2)CH_(3))]Cl`

Explanation

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

### (i) `[Co(NH3)6]Cl3`
1. Identify the central metal ion: Cobalt (Co).
2. Identify the ligands: There are 6 ammonia (NH3) ligands.
3. Name the ligands: Ammonia is named as "ammine". Since there are 6, it becomes "hexaammine".
4. Write the name of the metal: Cobalt.
5. Determine the oxidation state of cobalt: The three chloride ions (Cl-) contribute a total charge of -3. To balance this, cobalt must be in the +3 oxidation state.
