Mössbauer analysis of substituted diiron(II) tetraiminediphenolate macrocyclic complexes

A new series of substituted diiron(II) complexes [Fe2(tidf)(L)2(MeOH)2]n+ (tidf = a two compartment tetraiminediphenolate macrocycle; n = 0 or 2+; L = NCS−, CN−, N3−, pyrazine (pz), 4-cyanopyridine (4-cnpy) and 4-mercaptopyridine (4-shpy)) and one tetranuclear complex, {[Fe2(tidf)(CH3OH)2]2(μ-4-cnpy)2}(ClO4)4 were isolated and characterized by elemental analysis, conductivity measurements, Mössbauer and FTIR.
