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), ...

A 1,10-phenanthroline (phen) chelated molybdenum(VI) citrate, [(MoO2)2O(H2cit)(phen)(H2O)2] x H2O (1) (H4cit = citric acid), is isolated from the reaction of citric acid, ammonium molybdate and phen in acidic media (pH 0.5-1.0). A citrato oxomolybdenum(V) complex, [(MoO)2O(H2cit)2(bpy)2] x 4H2O (2), is synthesized by the reduction of citrato molybdate with hydrazine hydrochloride in the presenc...

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...

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...

The assimilatory nitrate reductase from Chlorella contains flavin, heme, and molybdenum as prosthetic groups. The molybdenum in assimilatory nitrate reductase is associated with a pterin moiety (molybdopterin) as evidenced by the ability of the enzyme to donate active molybdenum cofactor to the Neurospora nitrate reductase mutant nit-1 and by the oxidative conversion of the pterin to two well c...

Organometallic complexes offer potential for design as anticancer drugs. A quantitativemodel that discriminates anticancer compounds from the inactive ones in a training series wasEquilibrium of the reaction of molybdenum (VI) with l-histidine have been studiedin aqueous solutions at pH range of 4-8, using spectrophotometry and optical rotationmethods at constant ionic strength of 0.15 mol.lit-...

In earlier publication1, the authors have reported data on the polarographic behaviour of molybdenum(VI) in three different organic acid media viz. mandelic acid, succinic acid and formic acid — sodium formate and concluded that in medium comprised of 0.1 M mandelic acid, 0.005% thymol and 0.1% camphor Mo(VI) produces a well defined irreversible diffusion controlled doublet wave, the total heig...
