摘要

[ML(MeOH)Cl]Cl的对映体与M=MnII或FeII缔合形成手性一维配位化合物；L表示五齿大环的R或S对映体)和NBu4[FeIII(bpb)(CN)2]，即：1D-[{FeIII(bpb)(CN)2}{MII(LR)}]（PF6）和1D-[{FeIII(bpb)(CN)2}{MII(LS)}](PF6) M=Mn （2R, 2S）和Fe （3R, 3S）。描述了金属配体PNP[FeIII(bpb)(CN)2]·2H2O， 1b的双（三苯基膦）亚盐。报道了它们的制备、晶体结构、光学和磁性能。Mössbauer光谱证实了[FeII−FeIII]链中的氧化态，其交流磁化率表明SCM行为，但在非常低的T下。

Chiral 1D Cyanide-Bridged Bimetallic Compounds Build With Enantiomorphic Pentagonal Bipyrimidal M(II) Units

Chiral 1D coordination compounds formed by association of either of the enantiomers of [ML(MeOH)Cl]Cl (with M=Mn^II or Fe^II; L stands for either R or S enantiomer of a pentadentate macrocycle) and NBu₄[Fe^III(bpb)(CN)₂], namely: 1D-[{Fe^III(bpb)(CN)₂}{M^II(L^R)}](PF₆) and 1D-[{Fe^III(bpb)(CN)₂}{M^II(L^S)}](PF₆) with M=Mn (2R, 2S) and Fe (3R, 3S). The bis(triphenylphosphine)iminium salt of the metallo-ligand, PNP[Fe^III(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 [Fe^II−Fe^III] chain, for which AC susceptibility suggests SCM behavior, but for very low T.
