The complex ions [Fe(CN)_(6)]^(3-) and [Fe(CN)_(6)]^(4-) :
Answer»
Are both octahedral and PARAMAGNETIC Are both octahedral and diamagnetic Have same STRUCTURE but OPPOSITE magnetic character Have DIFFERENT structure but opposite magnetic character
Solution :`[Fe(CN)_(6)]^(3-)` is paramagnetic while `[Fe(CN)_(6)]^(4-)` is diamagnetic.
