Strong field low spin

WebJun 16, 2024 · CN−, a strong-field, π acceptor AND σ donor ligand, promotes low-spin complexes, since electron-pair repulsions are maximized and the crystal field splitting energy increases significantly. How you fill orbitals for low-spin complexes is to follow Hund's rule for that energy level, allowing electron pairing, then go to the next energy level. WebSolution Crystal field theory According to the crystal field theory, the complex can be classified as high spin or low spin. The high spin complex is the compound with the greatest number of unpaired electrons. There are fewer unpaired electrons in the low spin complex. High spin complexes have low crystal field splitting energy
