# Why [MnCl6]^2- has got 4 unpaired electrons instead of 3?

In $\ce{[MnCl_6]}^{2-}$, $\ce{Mn}$ has +4 oxidation state which gives it a $\ce{3d^3}$ $\ce{4s^0}$ configuration. But how is it having 4 unpaired electrons?

• are you sure it was 2- , I mean the charge can be 3- on the complex. – DSinghvi Apr 8 '15 at 9:20
• The complex you are asking about has an odd number of electrons, there is no way it can have four unpaired electrons. With three unpaired electrons it is in a quartet state though. Can you refer us to the source of your doubts, maybe it is a typo in a textbook. – Martin - マーチン Apr 9 '15 at 4:06
