Possible Isomers of [Co(H2NCH2CH2NH2)2Cl2] and [Co(H2NCH2CH2NH2)3]3

There are two compounds given in the question - [Co(H2NCH2CH2NH2)2Cl2] and [Co(H2NCH2CH2NH2)3]3. The question is asking for the total number of possible isomers of these compounds together.

[Co(H2NCH2CH2NH2)2Cl2]

This compound has two ethylenediamine (en) ligands and two chloride ions. The en ligands can be arranged in different ways around the central cobalt ion, giving rise to different isomers. The possible isomers are:

- Cis-cis isomer (both en ligands are on the same side of the molecule)
- Trans-trans isomer (both en ligands are on opposite sides of the molecule)
- Cis-trans isomer (one en ligand is on the same side as one chloride ion, and the other en ligand is on the opposite side)
- Trans-cis isomer (one en ligand is on the opposite side as one chloride ion, and the other en ligand is on the same side)

[Co(H2NCH2CH2NH2)3]3

This compound has three en ligands. The en ligands can be arranged in different ways around the central cobalt ion, giving rise to different isomers. The possible isomers are:

- Meridional isomer (all three en ligands are in the same plane)
- Facial isomer (two en ligands are on one side of the molecule, and the third en ligand is on the opposite side)

Total Number of Possible Isomers

To find the total number of possible isomers, we need to multiply the number of isomers for each compound. Therefore, the total number of possible isomers of [Co(H2NCH2CH2NH2)2Cl2] and [Co(H2NCH2CH2NH2)3]3 together is:

4 isomers for [Co(H2NCH2CH2NH2)2Cl2] x 2 isomers for [Co(H2NCH2CH2NH2)3]3 = 8 isomers

Conclusion

The total number of possible isomers of [Co(H2NCH2CH2NH2)2Cl2] and [Co(H2NCH2CH2NH2)3]3 together is 8. The possible isomers for [Co(H2NCH2CH2NH2)2Cl2] are cis-cis, trans-trans, cis-trans, and trans-cis. The possible isomers for [Co(H2NCH2CH2NH2)3]3 are meridional and facial.
