Final answer:
MLCT refers to Metal-to-Ligand Charge Transfer, which occurs when an electron is transferred between a metal ion in a complex and a ligand. The most common ligands to result in MLCT are those with high electron-donating abilities, such as cyanide (CN-) and water (H2O).
Step-by-step explanation:
MLCT refers to Metal-to-Ligand Charge Transfer, which occurs when an electron is transferred between a metal ion in a complex and a ligand. The most common ligands to result in MLCT are those with high electron-donating abilities, such as cyanide (CN-) and water (H2O). These ligands have lone pairs of electrons that can interact with the metal ion, leading to a transfer of charge.
