characterized and evaluated as the functional models for the carbon-carbon bond-cleaving catechol dioxygenase enzymes. The molecular structure of complexes 1 and 3 revealed a distorted octahedral geometry around iron(III) center with facial coordination of ligands via three nitrogen atoms and three chloride ions occupy the remaining sites of the octahedron. Iron(III) catecholate adducts were generated
