The hybridisation of manganese in potassium permanganate (KMnO4) is sd3.This is formally a manganese(VII) compound and hence there are no 3d electrons.The fourO2− ions are considered to be donating two electrons each to the atomic orbitals. Tetrahedral "hybridisation" can be achieved by using the4s,3dxy,3dyz and3dxz AOs. Since in Mn(VII) the3d AOs are lower in energy than the4s and4p AOs, the "hybridisation" is best considered as sd3
