The reaction of Fe2+ with CN-, which was first performed in 1704, has been used to synthesize a new series of basic [FeII,III(CN)4L2]n- complexes, where L is a monodentate ligand. trans-Na2[FeII(CN)4(DMSO)2] and cis-[NEt4]2[FeII(CN)4(pyridine)2] are synthesized by the direct reaction of FeCl2 with 4 equiv of CN- in DMSO or pyridine. Air oxidation of the latter compound gives cis-[NEt4][FeIII(CN)4(pyridine)2]. The non-cyanide ligands in these complexes undergo facile ligand exchange reactions with solvent. Reaction of cis-[NEt4]2[FeII(CN)4(pyridine)2] with CO at room temperature gives trans-[NEt4]2[FeII(CN)4(pyridine)(CO)].
Fe2+与CN-的反应最早于1704年进行,已被用于合成一系列新的碱性[FeII,III(CN)4L2]n-配合物,其中L是单齿配体。通过FeCl2与4当量的CN-在二甲基亚砜(DMSO)或吡啶中直接反应合成反式-Na2[FeII(CN)4(DMSO)2]和顺式-[NEt4]2[FeII(CN)4(pyridine)2]。后一种化合物的空气氧化得到顺式-[NEt4][FeIII(CN)4(pyridine)2]。这些配合物中的非氰化物配体与溶剂容易发生配体交换反应。顺式-[NEt4]2[FeII(CN)4(pyridine)2]在室温下与CO反应得到反式-[NEt4]2[FeII(CN)4(pyridine)(CO)]。
