“…Oxidation states ?2 and ?3 are the most widespread among the halides of iron with the stability of the trihalides decreasing toward the larger halides [8]. Thus, while iron triiodide cannot be evaporated without decomposition, iron diiodide is a well-known substance with interesting magnetic behavior [9,10] and different applications, such as in discharge lamps [11] or for preparation of nanowires through chemical vapor deposition [12]. Since this is the only iron dihalide whose molecular structure has not been determined yet, augmenting our computational study, we also determined the FeI 2 structure by high-temperature gas-phase electron diffraction.…”

The molecular structures, vibrational frequencies, and thermodynamic properties of all four monomeric and dimeric iron dihalide molecules, FeF 2 , FeCl 2 , FeBr 2 , and FeI 2 , were determined by quantum chemical calculations and the structure of iron diiodide also by gas-phase electron diffraction (ED). The earlier ED study of iron dibromide was also repeated. All iron dihalides are stable molecules in contrast to the iron trihalides, for which FeBr 3 and FeI 3 are unstable and easily decompose to the corresponding dihalides. The structures of the trimers and tetramers of FeCl 2 were also calculated and compared to the crystal structure.

“…Because of its high sensitivity and selectivity, 1C has largely displaced ion selective electrodes (ISES) for these types of determinations. Table 4 Typical concentration results (ug/g (ppm)) results for the trace analysis of Sc metal by GDMS and SC'3 by SSMS Applications to lamp materials include determination of trace chloride and bromide in metal iodide dose materials (55), and the evaluation of halide levels (F-, Cl-, Br-, and I-) in discharge arc tubes and halogen lamps. 8.5 Methods for trace C,~ and H impurities Coulometric Karl Fischer (KF) titration has been applied to the trace determination of ~i~~, OHand oxide in metal halide dose materials (115).…”

Iron, the most abundant transition element in the biosphere, is essential in higher forms of life and its compounds have numerous industrial applications. The element has catalytic properties. Several simple iron compounds are industrially important, for example, large amounts of iron oxides are produced for pigment and magnetic recording media applications. Oxidation states ranging from −2 to +6 are known, the most familiar are +2 (ferrous iron) and +3 (ferric iron). Most common complexes are octahedral, although examples of higher (e.g. seven coordinate) and lower (e.g. tetrahedral and square planar) geometries are well known, as are a variety of mixed oxidation state compounds. Depending on ligands involved high‐ and low‐spin complexes can be formed, and temperature‐dependent spin‐state crossover complexes are well documented. The thermodynamics and kinetics of reactions of low‐spin iron(II) complexes with ligands such as 1,4‐diimines and CN − have been extensively studied. While low‐spin iron(II) is present in biological systems such as oxygenated heme centered oxygen carriers and thiolate clusters, iron(III) is more common. Thiolate‐containing iron clusters form readily, and here mixed oxidation states are a prominent feature that is exploited in some important electron transfer proteins. Microorganism iron uptake is facilitated by tris‐catecholate and tris‐hydroxamate ligands like enterobactin that have an extraordinarily high affinity for iron(III) that results in a dramatic enhancement of the 3+ relative to the 2+ state in terms of redox potential.
