The complex ion Fe(CN)₆^4- (no unpaired electrons) is classified as A) There is no way to tell. B) strong field. C) weak field.

Question

Quizplus · Accepted Answer

The complex ion Fe(CN)6^4- has strong field ligands (CN^-) which will cause a large splitting of the d-orbitals, resulting in high crystal field stabilization energy (CFSE). As a result, all the electrons are paired up in the d-orbitals, making it a low-spin complex.
