Treatment of iron(II) chloride or iron(II) bromide with 2 equiv of sodium quinaldate (qn = quinaldate or C 10 H 6 NO 2 − ) yields the coordinatively unsaturated mononuclear iron(II) quinaldate complexes Na[Fe II (qn) 2 Cl]·DMF and Na[Fe II (qn) 2 Br]·DMF (DMF = N,N-dimethylformamide), respectively. When a similar synthesis is carried out using iron(II) triflate, a solvent-derived linear triiron(II) complex, [Fe II 3 (qn) 6 (DMF) 2 ], with two five-coordinate iron(II) centers and a ...
