WebHigh Spin and Low Spin Electron configurations for octahedral complexes, e.g. [M(H2O)6]n+. Only the d4through d7cases can be either high-spin or low spin. Δ< Π Δ> … The six bonding molecular orbitals that are formed are "filled" with the electrons from the ligands, and electrons from the d-orbitals of the metal ion occupy the non-bonding and, in some cases, anti-bonding MOs. The energy difference between the latter two types of MOs is called ΔO (O stands for octahedral) and is determined by the nature of the π-interaction between the ligand orbitals with the d-orbitals on the central atom. As described above, π-donor ligands lead to a s… WebStrong-field ligands, such as CN − and CO, increase the Δ splitting and are more likely to be low-spin. Weak-field ligands, such as I − and Br − cause a smaller Δ splitting and are more likely to be high-spin. Some octahedral complexes exhibit spin crossover, where the high and low spin states exist is dynamic equilibrium. flank steak with mushroom sauce

In case of strong ligands, pairing of electrons will be higher. Therefore, they are low-spin complexes. Therefore, strong field ligands such as cyanide produce low spin complexes and high field splitting. Therefore, the correct option is (c).

WebThe crystal field theory (CFT) is an electrostatic model which considers the metal-ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand. Ligands are treated as point charges in case of anions or dipoles in case of neutral molecules. definition.
