I have a question on VO2+ complex. I know that vanadium in VO2+ has +4 oxidation state and it has an unpaired electron in the d-orbital. Based on the notes, they have mentioned that for d4 onwards to d7 has 2 possibilities of arrangement of electrons i.e. high spin and low spin. However, for vanadium in VO2+ only has 1 arrangement since it is d1. It is coordinated with 2 acetylacetone ligands (based on my understanding, it is a weak field ligand), then for the arrangement of electron, does the complex have a high or low spin?
