“…It has been claimed since a long time that MoI 3 is isostructural with MoBr 3 , and thus possesses polymeric chains built of MoI 6 octahedra with shared opposite faces: 1 [MoI 6/2 ]∞ with short Mo–Mo bonds along the chain , . This was recently confirmed by careful refinement of the powder diffraction pattern from a sample of MoI 3 obtained by reductive iodination of MoCl 5 with SiI 4 at 150 °C . MoI 2 was shown to have the same cluster structure as MoCl 2 , which can be rendered as [(Mo 6 I 8 )I a 2 I a–a 4/2 ] two‐dimensional cluster coordination polymer (Figure ) .…”

“…Even MoI 5 was claimed as a black powder resulting from reaction of MoCl 5 with CH 3 I, C 2 H 5 I or CH 2 I 2 after 15 h heating; the product was characterized by elemental analysis and was found to be ESR‐silent .

“…The ground state undergoes Jahn–Teller distortion, which is apparent from the nature of the thermal ellipsoid of the central Mo atom. This anion can be regarded as a cutout fragment of the one‐dimensional chain MoI 6/2 , found in crystalline MoI 3 with Peierls distorted infinite chains in which Mo–Mo distances alternate with 2.842(3) and 3.571(3) Å . The [Mo 3 I 12 ] 3– ion reacts with phosphanes (PMe 3 , dppe) to form products of lower nuclearity.…”

“…Another preparative way is to make MoI 3 first and then to decompose it at 400 °C . The most recent way of making MoI 2 is based upon a solid state halide metathesis between MoCl 5 and SiI 4 . Crystal structure of MoI 2 was reported in 1982, and that of WI 2 in 1995 …”

This review is dedicated to the chemistry of Mo iodides. These compounds have a humble origin, and for a long time their chemistry has been almost completely neglected. Although important work on mononuclear and dinuclear Mo iodide complexes was done in 1980-1990s, the situation has dramatically changed within the last decade. The finding that the IntroductionThe iodides of transition metals attract much less attention than their chloride and bromide analogues, even though a book dealing exclusively with metal iodides was published half a century ago. [1] This is partly explainable by general lack of current or proposed practical use for this class of compounds. A notable exception offer the volatile iodides of Ti, Zr, and Hf, and of a few other metals, that can be used in the iodide process of van Arkel and de Boer. [2] Among the group 6 metals, this process can be applied for preparation of high purity chromium, which [a] Nikolaev His research interests focus on the coordination chemistry of 4d and 5d transition metals. Maxim Mikhaylov was born in Novosibirsk, (Russia). In 2009-2013 he completed his Ph. D. at the Laboratory of cluster and supramolecular compounds in the Nikolaev Institute of Inorganic Chemistry (NIIC) under suporevision of Prof. Dr. M. N. Sokolov. Now he is a researcher working in the Laboratory of synthesis of cooridnation compounds at NIIC. His research interests include synthesis of novel clusters and cluster complexes for the development of new materials.

“…Practical experience has shown that the straightforward solid‐state reaction of the elements in fused silica does not proceed in an easy way and requires careful handling, and the corresponding reaction for tungsten is ineffective. [18b] This prompted us to develop new methods for the preparation of W 6 I 12 and Mo 6 I 12 for subsequent ligand‐substitution reactions. At this point, we designed new compounds containing [M 6 I 8 L 6 ] 2– clusters (M = W, Mo) with various ligands (L).…”

Compounds containing the [Mo6I8L6]2– ion in which L is an inorganic or organic ligand show remarkable photophysical properties. Similar properties were observed for the corresponding compounds based on octahedral tungsten clusters. The properties of these photosensitizers are significantly impacted by the six outer iodide ligands of [W6I8I6]2–. To analyze the role of the outer ligands, we prepared and structurally characterized octahedral tungsten cluster compounds with [W6I8I6]2– and [M6I8L6]2– ions (M = W, Mo; L = para‐toluenesulfonate). The distinct photophysical properties of the clusters were analyzed with respect to their photoluminescence (i.e., phosphorescence) and luminescence quenching in the presence of molecular oxygen. The electronic structures were analyzed through photoelectron spectroscopy to expose differences in the electronic situations of the compounds.

Reaction of Mo(CO) 6 with Bu 4 NI and I 2 in diglyme yielded a new butterfly Mo III cluster [Mo 4 OI 12 ] 2-. The structure of tetraphenylphosphonium salt was determined by X-ray single crystal diffraction. Ph 4 P + and Bu 4 N + salts were further characterized by elemental analy-* Dr. M.
