A cloud-point preconcentration process using micelle of the non-ionic surfactant Triton X-114 to extract Mo(VI) from aqueous solutions was investigated. The method is based on the color reaction of molybdenum with 5-(2-benzothiazolyl-azo)8-hydroxy-quinoline (BTAHQ) in the presence of potassium bromide at pH 1.75 glycine/HCl buffer media and micelle-mediated extraction of complex. The optimal ex...

The bis(tert-butylimido)-molybdenum(VI) framework has previously been used for the successful atomic layer deposition (ALD) and chemical vapor of many molybdenum-containing thin films. Here, we have prepared fully characterized a new thermally robust bis(tert-butylimido)molybdenum(VI) complex, bis(tert-butylimido)-bis(N-2-(tert-butyliminomethyl)pyrrolato)-molybdenum(VI), (tBuN)2Mo(PyrIm)2 (1), ...

The reaction of Na2MoO4 with 2,2'-oxydianiline (2-aminophenylether), (2-NH2C6H4)2O, LH4, in DME (DME = 1,2-dimethoxyethane) in the presence of Et3N and Me3SiCl afforded either the bis(imido) molybdenum(vi) complex {Mo(L)Cl2(DME)} (), where L = (2-NC6H4)2O, or the molybdenum(v) salt [Mo(L')Cl4][Et3NH] (), where L' = [(2-NH2C6H4)(2-NC6H4)O], depending on the work-up method employed. The same diam...

Inspired by the reactivity of (per)chlorate reducing molybdoenzymes and encouraged lack molybdenum-containing functional models thereof, two molybdenum(VI) complexes type [MoO2L2] (L = pyrimidine-2-thiolate or 6-methylpyridine-2-thiolate) were found to be active homogeneous catalysts for reduction ClO4– ClO3– in CH2Cl2 using PPh3 as sacrificial oxygen acceptor. The subsequent stepwise Cl– is fa...

Acetophenone 2’,4’-dihydroxy semicarbazone (A24DHS) as a photometric reagent for the extractive spectrophotometric determination of Molybdenum (VI) is presented in this paper. The reagent A24DHS gave instantaneous and stable yellow colour with Molybdenum (VI) in the pH range 1.6 to 2.4. The system obeys Beer’s law in the concentration range of 1.0 μg/mL to 8.0 μg/mL at 370 nm. The Limit of Dete...

Molybdenum(VI) oxide reacts with molten LiC1-KCI eutectie at 450 ~ to form MOO2C12, which probably is present as an anion MoO2Cl4 =, and pyromolybdate, Mo207 =. Both of these species are electrochemically reduced to MOO2, which can be reoxidized to MoO2CI2 by current reversal. A second reduction step, observed whether MoO3 or Mo2072is added to the melt, can be attributed to the reduction of MoO...

The new carboxylato-dinitrosyl-molybdenum complexes o f the formula: [M o(NO )2( 0 2CMe)2] • MeOH, N a2[M o(NO)2( 0 2CMe)4] and M o(N O )2( 0 2CPh)2 have been synthesized. Their structure was resolved on the basis o f spectroscopic investigations ('H N M R , IR, U V -V IS ). Catalytic activity o f these complexes in olefin metathesis reaction was also examined. The electronic structure o f dini...

Formate dehydrogenase H from Escherichia coli contains selenocysteine (SeCys), molybdenum, two molybdopterin guanine dinucleotide (MGD) cofactors, and an Fe4S4 cluster at the active site and catalyzes the two-electron oxidation of formate to carbon dioxide. The crystal structures of the oxidized [Mo(VI), Fe4S4(ox)] form of formate dehydrogenase H (with and without bound inhibitor) and the reduc...
