Abstract: Chiral 1D coordination compounds formed by association of either of the enantiomers of [ML(MeOH)Cl]Cl (with M=MnII or FeII; L stands for either R or S enantiomer of a pentadentate macrocycle) and NBu4[FeIII(bpb)(CN)2], namely: 1D‐[{FeIII(bpb)(CN)2}{MII(LR)}](PF6) and 1D‐[{FeIII(bpb)(CN)2}{MII(LS)}](PF6) with M=Mn (2R, 2S) and Fe (3R, 3S). The bis(triphenylphosphine)iminium salt of the metallo‐ligand, PNP[FeIII(bpb)(CN)2]⋅2H2O, 1 b, is also described. Their preparations, crystal structures, optical and magnetic properties are reported. Mössbauer spectroscopy confirmed the oxidation state in the [FeII−FeIII] chain, for which AC susceptibility suggests SCM behavior, but for very low T.
