High Spin Complex
What is High Spin Complex?
A high-spin complex is a coordination compound in which the ligand field splitting energy (Δ) is smaller than the electron pairing energy, causing d-electrons to occupy higher-energy d-orbitals rather than pairing in lower-energy orbitals. This results in the maximum number of unpaired electrons, making the complex paramagnetic. High-spin complexes are typically formed with weak-field ligands such as halides, water, and hydroxide, and are common in first-row transition metal complexes.
