The reaction of iron(II) acetate with the tetradentate Schiff base like ligand H 2 L [(E,E)‐[{diethyl 2,2’‐[4,5‐dihydroxy‐1,2‐phenylenebis(iminomethylidyne)]bis3‐oxobutanato}]) leads to the formation of the octahedral N 2 O 4 coordinated complex [FeL(MeOH) 2 ] · MeOH ( 1 ). Conversion of 1 with N‐methylimidazole (N‐meim) leads to the N 4 O 2 coordinated complex [FeL(N‐meim) 2 ] · MeOH ( 2 ). Both complexes are pure HS compounds that were characterised using magnetic measurements and X‐ray crystallography. A special attention was given to the role of the two hydroxyl groups at the phenyl ring on the formation of a hydrogen bond network and the influence of this network on the magnetic properties.
