[Mo12S12O12(OH)12(H2O)6]: A Cyclic Molecular Cluster Based on the [Mo2S2O2]2+ Building Block

Control of the modularity of {Mo2O2S2}-containing polyoxometalates. Synthesis, structure and characterization of tri- and tetra-modular assemblies based on the [β-B-AsW9O33]9− anion

“…Actually, this P@O group is involved in the coordination of one {Mo 2 O 2 S 2 }, at the origin of the extended modularity. 4 can be roughly described as two pseudo-dimers connected through direct Mo-(l-OH) 2 -Mo bridges, a coordination scheme at the origin of the formation of the cyclic {Mo 2 O 2 S 2 } based rings [60]. Such a mode of coordination was recently observed with the oxo derivative {Mo 2 O 4 } 2+ cation, where the Mo-(l-OH) 2 -Mo connections lead to two basket handles grafted on the both sides of the {P 8 W 48 O 184 } nÀ macrocycle [61].…”

Discovery of gigantic molecular nanostructures using a flow reaction array as a search engine

“…All solutions were prepared with deionized water and stored in glassware after preparation. The [Mo 2 O 2 S 2 ] 2+ solution (containing (CH 3 ) 4 N + and I − ions) was prepared according to the literature procedure31 and it was always stored in Ar till used. The reagent stock solutions were prepared as follow: Na 2 MoO 4 ·2 H 2 O (4.84 g, 20 mmol) was dissolved in water and made up to 100 ml to give a 0.2-M molybdenum stock solution.…”

Characterization and catalytic performance of {Mo2O2S2}-based oxothiomolybdenum cyclic clusters supported on mesoporous SBA-15

“…Sample quantity is 0.5 μL with a split ratio of 10:1. [12]. IR (KBr pellet): the absorption peaks at 970, 525 and 488 cm − 1 attributed to vibrations of ν(Mo_O), ν(Mo\OH\Mo) and ν(Mo\S\Mo), respectively.…”

“…The structure of Mo 12 BTC can be described as a dodecanuclear ring encapsulated with a benzenetricarboxylate anion, each carboxylate group bridging two Mo centers (Fig. S1c) [9,12]. (200) planes of ordered hexagonal mesoporous materials (Fig.…”

“…So adding active elements onto the inner surface of the SBA-15 is a necessary process [11]. In this study, three [Mo 2 O 2 S 2 ]-based wheels: K 2 − x (NMe 4 ) x -[I 2 Mo 10 O 10 S 10 (OH) 10 (H 2 O) 5 [12] were loaded on an SBA-15 mesoporous material by the impregnation method. The thiophene hydrodesulfurization performance for the supported catalysts was investigated at four temperatures, respectively.…”
