Two polymorphs of iron(II) complex fac-[FeII(HLn-Pr)3]Cl·PF6, 1 and 2, were obtained (HLn-Pr=2-methylimidazole-4-yl-methylideneamino-n-propyl ligand). Complex cations, fac-[FeII(HLn-Pr)3]2+, of 1 and 2 had similar octahedral and facial geometries coordinated with three bidentate HLn-Pr ligands. The three imidazole groups in fac-[FeII(HLn-Pr)3]2+ with Δ- and Λ-enantiomorphs are hydrogen-bonded with...
