The coordination number of Co in \([Co(NH_3)_4Cl_2]Cl\) is
Show Hint
- 2
- 3
- 4
- 6
The Correct Option is D
Solution and Explanation
Step 1: The coordination number is determined by counting the number of ligands directly attached to the central metal atom.
Step 2: In \([Co(NH_3)_4Cl_2]Cl\), cobalt is surrounded by four \( NH_3 \) ligands and two \( Cl^- \) ligands, making a total coordination number of 6.

What type of isomerism is shown by the complex \([\text{Co(NH}_3)_6][\text{Cr(CN)}_6]\)?
The given coordination compound \([\text{Co(NH}_3)_6][\text{Cr(CN)}_6]\) exhibits ionization isomerism.
**Explanation:** Ionization isomerism arises when two complexes have the same molecular formula but yield different ions in solution. In this case, the cationic complex \([\text{Co(NH}_3)_6]^{3+}\) and the anionic complex \([\text{Cr(CN)}_6]^{3-}\) could interchange their ligands under different conditions, leading to a different complex with distinct properties.
