Webi. High-spin complexes: When crystal field splitting energy is greater than electron pairing energy, the complexes formed are high-spin complexes. ii. Low-spin complexes: When crystal field splitting energy is smaller than electron pairing energy, the complexes formed are low-spin complexes. Concept: Theories of Bonding in Complexes WebThe high-spin configuration, t 4 2g e 2 g , is adopted when relatively weak-field ligands are coordinated while the low-spin, t 6 2g e 0 g , is obtained when strong-field ligands are involved.
