化合物（pyH） 3Fe2Cl9和（pyH） 3Fe2Br9的磁化率、光谱和Móssbauer光谱表明，它们不像一些作者认为的那样含有µ-三晕二聚阴离子（Fe2X9） 3，而是铁完全以四面体的形式存在。制备了两种形式的Cs3Fe2Clg。一种可能类似于吡啶化合物，即[CsFeCL] 2-CsCl，而另一种则含有µ-三氯二聚阴离子。报道了卤代铁吡啶的低温电子能谱，并讨论了谱带的归属。在研究多核过渡金属配合物中金属-金属相互作用的过程中，我们研究了化合物（pyH） 3Fe2Cl9和（pyH） s-Fe2Br9 （py=吡啶）。由于这项工作，我们得出了一个结论，与早期的工作相比，令人惊讶的是，这些化合物中的铁完全以四面体配位单体阴离子的形式存在。四氯化物是由Weinlandand Kissling首先描述的，他同时报道了化合物（QH） 4Fe2Clio （Q=）
The magnetic susceptibilities, optical spectra, and Móssbauer spectra of the compounds (pyH) 3Fe2Cl9 and (pyH) 3Fe2Br9 indicate that they do not contain the µ-trihalo dimeric anion (Fe2X9) 3-as suggested by several authors, but rather that the iron is entirely present as tetrahedral FeX,-. Two forms of Cs3Fe2Clg have been prepared. One is probably like the pyridinium compounds, ie,[CsFeCL] 2-CsCl, while the other contains the µ-trichloro dimeric anion. Low temperature electronic spectra of the pyridinium iron halides are reported and the assignments of the bands are discussed.During the course of an investigation of metal-metal interactions in polynuclear transition metal complexes we examined the compounds (pyH) 3Fe2Cl9 and (pyH) s-Fe2Br9 (py= pyridine). As a result of this work we came to the conclusion, surprising in the light of earlier work, that the iron in these compounds is present en-tirely as a tetrahedrally coordinatedmonomeric anion. The enneachloride was first described by Weinlandand Kissling, 1 who at the same time reported the compounds (QH) 4Fe2Clio (Q=
