The compound dichloro(l,3-dibenzoyl-2-azapropenato)(ethanol)iron(III), Fe(C16H12NO2)Cl2(C2H50H), has been prepared, and its structure has been determined crystallographically. The compound was prepared by the reaction of iron(II) chloride with a-aminoacetophenone in the presence of air. The structure consists of octahedral iron(III) coordinated by two chlorides, an ethanol, and a tridentate ligand derived from two molecules of a-aminoacetophenone by oxidation and condensation. The two five-membered rings of the ligand are virtually identical. The compound crystallizes in monoclinic space group C2/c with eight formula units in a unit cell of dimensions a=29.606 (8) υ, b=6.689 (1) υ, c=20.627 (6) υ, β=114.70 (2)°, PcaM=1.51 g/cm3, and pobsd=1.51 g/cm3. The structure was solved by Patterson methods, and least-squares refinement converged at final values of R=0.066 and Rw=0.045 for 1729 reflections with I ≥ 2δs(I).
