Trichlorido[(methyl{2-[methyl(2-pyridylmethyl)amino]ethyl}amino)acetonitrile]iron(III) methanol hemisolvate

A. Nielsen, C. J. McKenzie and A. D. Bond

Abstract: The title compound, [FeCl₃(C₁₂H₁₈N₄)]·0.5CH₃OH, contains an Fe^III ion in a distorted octahedral coordination environment. The neutral N,N',N''-tridentate ligand adopts a fac coordination mode, and chloride ligands lie trans to each of the three coordinated N atoms. In the crystal, the complexes form columns extending parallel to the approximate local threefold axes of the FeN₃Cl₃ octahedra, and the columns are arranged so that the uncoordinated nitrile groups align in an antiparallel manner and the pyridyl rings form offset face-to-face arrangements [interplanar separations = 2.95 (1) and 3.11 (1) Å; centroid-centroid distances = 5.31 (1) and 4.92 (1) Å]. The methanol solvent molecule is disordered about a twofold rotation axis.
