The title complex, [Fe(NCS) 2 (C 32 H 46 N 4 O 2 ) 2 ], is a mononuclear iron(II) complex with a distorted octahedral coordination geometry and the central Fe 2+ ion, located on an inversion centre, is coordinated by four N atoms and two O atoms from two Schiff-base ligands and two thiocyanate anions. The Schiff base was obtained by condensation of
