For an octahedral iron(II) complex to be paramagnetic, it must have unpaired electrons. Iron(II) has a d^6 configuration. A high spin complex occurs when the crystal field splitting energy (Δ) is small, allowing electrons to occupy higher energy orbitals with parallel spins (according to Hund's rule), resulting in unpaired electrons and paramagnetism.
