D, Ahmed. Chemical Formula = [ Fe (C₁₆H₁₂NO₂) Cl₂ (C₂H₅OH) ]

Iron(III) has a C.N. = 6, and an approximate octahedral symmetry. The tridentate ligand occupies mer sites, and the two chloride anions are cis. One of the chloride anions is trans to the nitrogen of the tridentate ligand, so the ethanolate anion is trans to the remaining chloride anion.
