In the compound, CaNa[Fe(CN)₆], what ligands are in the coordination sphere? A)Ca²⁺ B)Na⁺ C)CN^- D)H₂O E)none of the above

Question

Quizplus · Accepted Answer

In the compound, CaNa[Fe(CN)S1U1B16S1U1B0], the central metal ion is Fe, which is coordinated to CN- ligands. The CN- ligand is a strong field ligand, which will form a high spin complex with Fe which means that S1U1P1- groups will bind with Fe too. Na+ ion is not in the coordination sphere because it is present outside the bracket. Ca2+ ion is in the coordination sphere but it will not coordinate to Fe because it is a larger ion than Fe and will form weaker bonds. Therefore, the only ligands in the coordination sphere are the sulfur-containing ligands, making choice C the correct answer.
