This article describes the synthesis, structures and systematic study of the spectroscopic and redox properties of a series of octahedral molybdenum metal cluster complexes with aromatic sulfonate ligands (BuN)[{MoX}(OTs)] and (BuN)[{MoX}(PhSO)] (where X is Cl, Br or I; OTs is p-toluenesulfonate and PhSO is benzenesulfonate). All the complexes demonstrated photoluminescence in the red region and an ability to generate singlet oxygen. Notably, the highest quantum yields (>0.6) and narrowest emission bands were found for complexes with a {MoI} cluster core. Moreover, cyclic voltammetric studies revealed that (BuN)[{MoX}(OTs)] and (BuN)[{MoX}(PhSO)] confer enhanced stability towards electrochemical oxidation relative to corresponding starting complexes (BuN)[{MoX}X].

“…Terminal iodide exchange in (Bu 4 N) 2 [Mo 6 I 14 ] with corresponding Ag salts was used for preparation of various complexes of the {Mo 6 I 8 } 4+ cluster core with O‐, S‐, and C‐donating organic ligands, including carboxylates, fluorinated aromatic thiolates, mono‐ and dinitrophenolates, alkynyl derivatives. In all cases, the six terminal ligands are exchanged, and no products corresponding to intermediate substitution steps were isolated , , . These reactions are transferable to [W 6 I 14 ] 2– , but in the case of the latter the yields are often less.…”

“…Another example of increased emissive performance of the combination ({Mo 6 I 8 } 4+ core plus fluorinated ligand) is given by comparison of the photophysics displayed by “conventional” thiolates [Mo 6 Cl 8 (SR) 6 ] 2– and [Mo 6 I 8 (SC 6 F 4 H) 6 ] 2– . Whereas for the Mo 6 Cl 8 4+ core coordination of thiolates favors non‐radiative relaxations, drastically reducing both the emission lifetime and quantum yields (as compared with [Mo 6 Cl 14 ] 2– ), for the iodide cluster introduction of the fluorinated thiolate increases these values relative to [Mo 6 I 14 ] 2– (all taken as TBA salts) …”

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.

“…The most studied are the derivatives of molybdenum chloride and bromide (M = Mo; X = Cl, Br). However, the less studied iodide Mo 6 clusters (X = I) stand out owing to their superior emission lifetimes and quantum yields as well as their narrow and blueshifted emission spectra in comparison with those of the other members of the {M 6 X 8 } cluster family with 24 cluster skeleton electrons , , . The tungsten clusters are less studied; in particular, very little is known about the chemistry of [{W 6 (µ 3 ‐I) 8 }L 6 ] clusters.…”

Complexes of {W₆I₈}⁴⁺ Clusters with Carboxylates: Preparation, Electrochemistry, and Luminescence

The reactions between (Bu4N)2[{W6I8}I6] (1) and silver carboxylates RCOOAg in CH2Cl2 afforded new luminescent carboxylate complexes (Bu4N)2[{W6I8}(RCOO)6] [R = CH3 (2), C6H5 (3), C2F5 (4), C3F7 (5), C6F5 (6)]. The complexes were characterized by single‐crystal X‐ray diffraction, elemental analysis, cyclic voltammetry, and IR and NMR spectroscopy. Complexes 1–6 all exhibit intense and long‐lived photoluminescence. The carboxylate complexes undergo reversible electrochemical oxidation in two consecutive one‐electron steps.
