In the coordination compound K₃[Fe(CN)₆], the coordination sphere is:
AFe³⁺
BCN⁻ only
CK₃
D[Fe(CN)₆]³⁻
Answer & Solution
Correct answer: D. [Fe(CN)₆]³⁻
**Coordination sphere** = central atom + ligands within the square brackets = **[Fe(CN)₆]³⁻**. K⁺ is the **counter ion** (outside the brackets). The coordination number of Fe³⁺ is 6.
