Four new cis-dioxomolybdenum(VI) complexes of the closed formula [MoO2(L)CH3OH] have been obtained by condensation bis(acetylacetonato)dioxomolybdenum(VI) with S-allyl/propyl thiosemicarbazones in methanol. The compounds were identified elemental analysis, and molecular characterization UV-Vis, FT-IR, 1H-NMR 13C-NMR spectroscopies. Also, crystal structures 1 2 resolved X-ray diffraction analysi...

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...

the molybdenum dicilicide is an intermetallic compound with two allotropies tetragonal ?-mosi2 and hexagonal ?-mosi2.the ?-mosi2 phase is established to 1900 ?c and ?-mosi2 phase from 1900 to 2050 ?c. this material has considerable properties that provide different applications in different industries such as air-space industry and gas turbines. the molybdenum synthesis can be down in various w...

In microaerophilic or anaerobic environments, Pseudomonas aeruginosa utilizes nitrate reduction for energy production, a process dependent on the availability of the oxyanionic form of molybdenum, molybdate (MoO4 (2-)). Here, we show that molybdate acquisition in P. aeruginosa occurs via a high-affinity ATP-binding cassette permease (ModABC). ModA is a cluster D-III solute binding protein capab...

Thirty cross-bred steers (initial BW 452.0 ± 12.1 kg) were used to investigate the effects of Mo water concentration on performance, carcass characteristics, and mineral status of feedlot steers. The experimental design was a randomized complete block design. Steers were blocked by weight and then divided into 2 weight blocks each consisting of 15 steers. Steers were randomly assigned within bl...

The geochemical behavior of molybdenum (Mo) in the oceans is closely linked to the presence of sulfide species in anoxic environments, where Fe availability may play a key role in the Mo scavenging. Here, we show that Mo(VI) is reduced in the presence of particulate organic matter (represented by sulfate-reducing bacteria). Molybdenum was immobilized at the surface of both living cells and dead...

The title polyanion is the first hybrid borophosphate-phenylphosphonate polyoxometalate. It was structurally characterized as its imidazolium salt, (C(3)N(2)H(5))(5)[Mo(12)O(30)(BPO(4))(2)(O(3)P-Ph)(6)].H(2)O (monoclinic, P2(1)/c, a = 22.120(3) A, b = 13.042(2) A, and c = 32.632(4) A, beta = 101.293(3) degrees ), which was synthesized hydrothermally from imidazole, molybdenum oxide and metal, a...
