A new organo-ruthenium substituted tungstotellurate: synthesis, structural characterization and catalytic properties

Abstract

A novel organo-Ru supported tungstotellurate(iv) has been synthesized and its catalytic activity was assessed towards the oxidation of n-tetradecane using air without any additives or solvents.

A Crown‐Shaped Ru‐Substituted Arsenotungstate for Selective Oxidation of Sulfides with Hydrogen Peroxide

“…It is still as ignificant challenge to synthesize multi-Ru-substituted polyoxotungstates. [20][21][22][23] In searching for an ew entry into RSKP chemistry,weu tilizedt he self-assembly strategy of sodium tungstate, heteroatom ingredients such as sodium arsenite, and ruthenium ions. In comparison, the introductiono ft rigonal-pyramidal XO 3 groups (X = As III ,S b III ,B i III ,S i IV ,G e IV )i nto Ru-substitutedp olyoxotungstates remains largely unexplored.…”

“…To date, only af ew RSKPs based on trigonal-pyramidal XO 3 groups( X= As III ,S b III ,B i III ,S i IV ,G e IV )h ave been characterized.

This approach for discovering novelR SKPs wasa dopted for the following rea-sons.…”

A Novel Ruthenium-Decorating Polyoxomolybdate Cs3Na6H[MoVI14RuIV2O50(OH)2]·24H2O: An Active Heterogeneous Oxidation Catalyst for Alcohols

“…Noble metals containing polyoxometalates (POMs), in particular ruthenium (Ru)-incorporating structures [1], have been widely implemented in homo-/heterogeneous oxidation catalysis of both organic [2,3,4,5,6,7,8,9,10,11,12,13] and water-splitting reactions [14,15,16,17,18], and have therefore been attracting ever-increasing attention in recent decades. Since the discovery of the first Ru-containing POM [SiW 11 O 39 RuL] n− in 1989 [2], this domain has been further explored by the research groups of Neumann, Sadakane, Bonchio, Pope, Nomiya, Proust, Hill, Bond, Kortz, Bi and others [19].…”

“…Among them, the wholly inorganic Ru-containing POMs represent an important subclass, which had been studied previously but with only a few structures reported as compared to those with inorganic-organic hybrid Ru-containing POMs. Up until now, the majority of investigations in this area of research have been dominated by the preparations and characterizations of Ru-substituted or -sandwiched lacunary Keggin/Dawson-type heteropolytungstates [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43], such as mono-Ru substituted polyanions [XW 11 O 39 Ru III (H 2 O)] n− (X = Si, Ge, P) [2,3,4,5,20,21,22,23,24,25] and [P 2 W 17 O 61 Ru III (H 2 O)] 5− [26,27,28], di-Ru-sandwiched/substituted polyanions {O[Ru IV (X)P 2 W 17 O 61 ] 2 } 16− (X = OH, Cl) [27], {[(XZnRu 2 III (OH)(H 2 O)](ZnW 9 O 34 ) 2 } n− (X = W, Zn) [29,30,…”

Rare-Earth-Incorporated Tellurotungstate Hybrids Functionalized by 2-Picolinic Acid Ligands: Syntheses, Structures, and Properties

“…In 2016, they addressed the unseen main-group-Ga III -containing sandwich-type TT [Ga 4 (H 2 O) 10 (β-TeW 9 O 33 ) 2 ] 4– . Very recently, Niu’s group and Bi’s group successively prepared Krebs-type TT-based organometallic derivatives [{Mn­(CO) 3 }­(Mn­(H 2 O) 2 )­(Mn­(H 2 O) 3 )­(TeW 9 O 33 )] 2 6– and [Te 2 W 20 O 70 (RuC 6 H 6 ) 2 ] 8– . , Notably, Cronin and collaborators have pioneered a oxopalladate cluster study with the discovery of the high-nuclear palladium TT cluster [Pd 6 Te 19 W 42 O 190 ] 40– . In the same year, their group communicated a series of nanosized multi-Ag I encapsulated poly­(TT) aggregates [H 10 Ag 18 Cl­(Te 3 W 38 O 134 ) 2 ] 29– , {[H 13 Ag 18 Cl­(Te 3 W 38 O 134 ) 2 ] 26– } 2 ,and {[H 15 Ag 18 Cl­(Te 3 W 38 O 134 ) 2 ] 24– } n by means of the time-resolved supramolecular assembly strategy …”
