The Complexes of Ti(iii), V(iii), Mn(iii), Co(iii), Ru(iii), Ru(ii), MoO(v), Fe(iii), MoO 2 (vi) and UO 2 (vi) with S-benzyl-β-N-(2-hydroxy-5-bromophenyl) methylendithiocarbazate have been synthesized and characterised by melting points, molar conductance,magnetic susceptibility, electronic and IR spectral studies. The complexes of Ti(iii), V(iii), Mn(iii), Ru(iii) & MoO(v) are paramagnetic whi...

Reduced size and direct electrochemical H2 compression are two distinct advantages of electrolyzers based on the acid-polymer electrolyte membrane technology over those relying on alkaline electrolytes. However, recourse to catalysts based on the scarce platinum-group-metals has hitherto been the price to pay. While the transition metal sulfides and nitrides of group VI have recently shown inte...

Speciation of actinide in natural aquatic system is of great interest for the safety assessment of a nuclear waste disposal in deep geological system [1]. Actinide ions form complicate complexes with various ligands such as OH, CO3, and humic substances in groundwater. These complexes can enhance or reduce the migration of actinide elements. The direct speciation of these complexes in groundwat...

The title salt, (C(5)H(6)N)(4)[Mo(2)Cl(2)O(5)(SO(4))(2)], comprises four pyridinium cations for each [(MoClO(2))(2)(μ-O)(μ-SO(4))(2)](4-) anionic unit. The asymmetric unit consists of three aggregates of the empirical formula. The tetra-anionic bimetallic molybdenum(VI) cluster is unprecedented and contains two sulfate and one oxide bridges. This structure constitutes the first example of a non...

Reaction of the tricarbon-yl{η(5)-[2-(dimethyl-amino)eth-yl]cyclo-penta-dien-yl}molybdenum anion and dichlorido-diphenyl-stannane affords the title compound, [MoSn(C(6)H(5))(2)Cl(C(9)H(14)N)(CO)(3)], which exhibits a four-legged piano-stool geometry with chlorido-diphenyl-stannyl ligands unperturbed by the pendant 2-(dimethyl-amino)ethyl groups. The Mo-Sn bond length [2.7584 (5) Å] and the dist...

Lithium(I) and uranium(VI) amido-tethered Bu(t)-substituted N-heterocyclic carbene (NHC) complexes exhibit very distorted metal-carbene bonds; the corresponding magnesium(II) and mesityl-substituted NHC uranium(VI) complexes are undistorted; the distortion does not affect the ligand binding strength, suggesting a dominance of electrostatic character in closed-shell electropositive metal-carbene...
