Q. What is Electronic Isomerism?
Electronic Isomerism: The complex {Co (NH3)sNO]Cl2 exists in two forms. One is black paramagnetic while the other is pink and diamagnetic. Thorough structural studies show that the black isomer is a Co(ll) complex containing neutral NO group whereas the pink one is a Co(111) complex where NO- ion is present. This kind of isomerism is known as electronic isomerism.
