Identify the coordination sphere in the compound K4[Fe(CN)6].(a) K^+(b

1.	Identify the coordination sphere in the compound K4[Fe(CN)6].(a) K^+(b) Fe^2+(c) [Fe(CN)6]^4-(d) CN^–I have been asked this question during an interview.Origin of the question is Definitions topic in chapter Coordination Compounds of Chemistry – Class 12
Answer» CORRECT answer is (c) [FE(CN)6]^4- To explain I would say: The coordination sphere refers to the square bracket WITHIN which the central atom/ion and the groups attached to it are enclosed. This is a non-ionisable group as compared to the ENTITY outside the bracket, which is ionisable and is known as the counter ion.
