In the title iron(II) complex, [Fe(C12H21N2Si)Cl(C6H16N2)], the FeII cation is coordinated by two N atoms from the tetramethylethane-1,2-diamine ligand [Fe-N = 2.191 (5) and 2.215 (4) Å], one N atom from the N-[(diethylamino)dimethylsilyl]anilide ligand [Fe-N = 1.943 (4) Å] and a chloride ligand [Fe-Cl = 2.2798 (16) Å] in a distorted tetrahedral geometry. The N-Si-N angle is 113.9 (3)°. The crystal packing exhibits no short intermolecular contacts.
