Abstract The magnetic properties of two octahedral iron(II) complexes with Schiff base like equatorial N 2 O 2 coordinating ligands and methanol (MeOH) as axial ligand are reported. Both compounds [FeL1(MeOH) 2 ] ( 1 ) and [FeL2(MeOH) 2 ] ( 2 ) (with L1 = [3,3′]‐[1,2‐phenylenebis(iminomethylidyne)‐bis(2,4‐pentanedionato)(2‐)‐N,N′,O 2 ,O 2 ′] and L2 = [E,E]‐[{diethyl 2,2′‐1,2‐phenylenebis(iminomethylidyne)bis(3‐oxo‐3‐phenylpropanato)} (2‐)‐N,N′,O3,O3′]) show a weak spontaneous magnetization below T C = 10 K. Results from X‐ray structure analysis of 1 indicate, that this is due to 2D network of hydrogen bonds as previously discussed for a similar complex.
