Select the incorrect match:

Options

A. `[Co(NO_(2))(H_(20O)(en)_(2)]Cl_(2),[CoCl(NO_(2))(en)_(2)]Cl*H_(2)O`: Hydrate isomerism
B. `[Cu(NH_(3))_(4)][PtCl_(4)],[CuCl(NH_(3))_(3)][}tCl_(3)(NH_(3))]`: Co-ordinatino isomersm
C. `[Ni(CN)(H_(2)O)(NH_(3))_(4)]Cl,[NiCl(H_(2)O)(NH_(3))_(4)]CN`: Ionization isomerism
D. `[Cr(NO_(2))(NH_(3))_(5)][ZnCl_(4)],[Cr(NO_(3))(NH_(3))_(5)][ZnCl_(4)]`: Linkage isomerism

Explanation

To solve the question of selecting the incorrect match among the given coordination compounds, we will analyze each option step by step.

### Step 1: Understand the Types of Isomers
Before evaluating the options, let's briefly understand the types of isomers mentioned:
1. **Hydrate Isomers**: Isomers that differ in the number of water molecules inside and outside the coordination sphere.
2. **Coordination Isomers**: Isomers that differ in the arrangement of ligands around the central metal atom.
3. **Ionization Isomers**: Isomers that differ in the ions produced when the compound is dissolved in water.
4. **Linkage Isomers**: Isomers that differ in the way ligands are attached to the central metal atom.

### Step 2: Analyze Each Option
1. **Option A**: CO, NO2, H2O, En2O2, Cl2, Cu, Cl, NO2, En2O2, Cl.H2O
- This option describes hydrate isomers. Since it involves the presence of water molecules, it is correctly matched.

2. **Option B**: CONH3O4, PTCl4 and COClNH3O3, PTCl3NH3
- This option describes coordination isomers. The ligands are arranged differently around the central metal, making this a correct match.

3. **Option C**: Ni-Cl-H2O-NH3O4-Cl and Ni-Cl-H2O-NH3O4-Cl
- This option claims to be ionization isomers. However, since both compounds are identical, they cannot be ionization isomers. Therefore, this option is incorrect.

4. **Option D**: CrNO2NH3O5 and ZnCl4, CrNO2NH3O5ZnCl4
- This option suggests linkage isomers. However, the ligands are not merely rearranged but differ in their chemical composition (NO2 vs NO3), which means they cannot be classified as isomers. This option is also incorrect.

### Conclusion
After analyzing all options, we find that:
- **Option C** is the incorrect match as it does not represent ionization isomers, but rather the same compound.

### Final Answer
The incorrect match is **Option C**.
