“…The steady state and time resolved luminescence data indicate concentration‐dependent sensitizing of the Mo‐centered luminescence through the energy transfer from difloxacin and other fluoroquinolone antibitics to [Mo 6 I 14 ] 2– in water in the presence of pluronics triblock copolymers, mediated by the ion‐pairing , . The energy transfer can be switched off by external stimuli, such as heating and changing concentration of the triblock copolymer in the solution.…”

“…The energy transfer can be switched off by external stimuli, such as heating and changing concentration of the triblock copolymer in the solution. Moreover, the energy transfer is very sensitive to the structure of fluoroquinolones, which enables to discriminate, e.g., between difloxacin and gatifloxacin, in one hand, and pefloxacin, norfloxacin, enrofloxacin, danofloxacin, lomefloxacin, and ciprofloxacin, in the other hand …”

“…Tribloc copolymers (PEO‐PPO‐PEO, Pluronics) and PPO‐PEO‐PPO (reverse Pluronics) stabilize aqueous solutions of [Mo 6 I 14 ] 2– for up to two days. Such solutions can be used as sensors, for example, to detect fluoroquinolone antibiotics via excitation transfer …”

“…These observations have made molybdenum iodide cluster complexes rather attractive for a diverse range of practical applications in biology and medicine (e.g. as photodynamic therapeutic agents, photosensitizers, imaging agents) and analytical chemistry (for detection of trace amounts of molecules which can trigger or quench the luminescence, such as dioxygen or fluoroquinolone antibiotics) , …”

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.

“…Octahedral halide cluster complexes of Mo II and W II , [{M 6 (µ 3 ‐X) 8 }L 6 ] (M = Mo or W; X = Cl, Br or I; L = neutral or anionic ligands), are chemically robust constructions with outstanding photophysical properties; therefore, they are potentially useful for various applications . The most studied are the derivatives of molybdenum chloride and bromide (M = Mo; X = Cl, Br).…”

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.

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. Mikhaylov 438 sis, mass spectrometry, energy-dispersive X-ray (EDX), IR, Raman, and UV/Vis spectroscopy and CVA studies. The cluster anion has a butterfly array of molybdenum atoms and can be represented as [Mo 4 (μ 4 -O)(μ 3 -I) 2 (μ 2 -I 4 )I 6 ] 2-.
