Trying to find the right answer to this..

octahedral) complex in which the d- orbital used are from the outer orbits are called outer octahedral compound complex. –(sp 3 d 2 ) As no pairing occurs in these complexes, they can have many unpaired electrons (from 1 to 5) and hence large value of magnetic moment. Therefore called high spin complexes.

Why outer octahedral complexes are celled high spin complexes?

octahedral) complex in which the d- orbital used are from the outer orbits are called outer octahedral compound complex. –(sp³d²)
As no pairing occurs in these complexes, they can have many unpaired electrons (from 1 to 5) and hence large value of magnetic moment. Therefore called high spin complexes.
