Cs3[CoCl4]Cl:
- In solid Cs3CoCl5, the coordination number of the cobalt ion can be determined by analyzing the crystal structure.
- It exists in solid as Cs3[CoCl4]Cl.
- Each cobalt ion is surrounded by four chloride ions, which form a distorted tetrahedral geometry around the cobalt ion. Therefore, the coordination number of the cobalt ion in Cs3CoCl5 is 4.
(NH4)3[ZnCl4]Cl:
- In solid (NH4)3ZnCl5, the coordination number of the zinc ion can be determined similarly.
- It exists in solid as (NH4)3[ZnCl4]Cl.
- Each zinc ion is surrounded by four chloride ions, forming a distorted tetrahedral geometry around the zinc ion. Hence, the coordination number of the zinc ion in (NH4)3ZnCl5 is also 4.
Hence, the coordination numbers of cobalt ion in solid Cs3CoCl5 and zinc ion in solid (NH4)3ZnCl5 are, respectively, 4 and 4.

The coordination numbers of cobalt ion in solid Cs3CoCl5 and zinc ion in solid (NH4)3ZnCl5 are 4 and 4, respectively.
Explanation:
The coordination number is the number of atoms or ions that surround a central atom or ion in a crystal lattice. It represents the number of nearest neighbors of the central atom or ion.
Coordination number of cobalt ion in Cs3CoCl5:
In the compound Cs3CoCl5, the cobalt ion is surrounded by chloride ions. The formula suggests that there are 5 chloride ions surrounding each cobalt ion. However, the coordination number is determined by the number of bonds formed between the central atom and its surrounding ligands. In this case, each chloride ion forms only one bond with the cobalt ion. Therefore, the coordination number of cobalt ion in Cs3CoCl5 is 4.
Coordination number of zinc ion in (NH4)3ZnCl5:
In the compound (NH4)3ZnCl5, the zinc ion is also surrounded by chloride ions. The formula suggests that there are 5 chloride ions surrounding each zinc ion. However, similar to the previous case, each chloride ion forms only one bond with the zinc ion. Therefore, the coordination number of zinc ion in (NH4)3ZnCl5 is also 4.
Conclusion:
The coordination numbers of cobalt ion in solid Cs3CoCl5 and zinc ion in solid (NH4)3ZnCl5 are both 4. Therefore, the correct answer is option B) 4 and 4.
