چکیده
Three discrete cobalt-substituted silicotungstates, [Co3(H2O)(B-beta-SiW9O34)(B-beta-SiW8O29(OH)2)]12- (1), [Co3(H2O)(B-alpha-SiW9O34)(B-beta-SiW8O31)]14- (2), and [Co9Cl2(OH)3(H2O)9(B-beta-SiW8O31)3]17- (3), have been synthesized using a synthetic approach involving Co(II) ions, the dilacunary [gamma-SiW10O36]8- polyanion and a bulky organic cation in basic media; all three compounds have been fully characterized and their position as structural intermediates in Co-containing silicotungstate chemistry is described.

Synthesis and structures of gold and copper carbene intermediates in catalytic amination of alkynes
Metal carbenes are often proposed as reactive intermediates in the late transition metal-catalysed transformations of alkynes. Owing to their high reactivity, however, isolation and structural characterization of metal carbene intermediates in these transformations has remained unknown. Herein, we report the isolation of two acyclic gold and copper carbene intermediates in either Au(I)- or Cu(I...

Transition-metal-substituted (TMS) polyoxometalates of the general formula [SiW9M3O39], (where M = first row transition metal), has been synthesized and supported on anatase by sol–gel method under oil-bath condition. The tetrabutylammonium (TBA) salts of the Keggin-type polyoxotungstates [SiW9M3O39], (M = VII, CrII, MnII, FeII CoII and NiII), proved to be green, reusable, and ...

Herein, we report for the first time polyoxometalate (POM)-based single-molecule magnets with mononuclear transition metal cores. The mononuclear Fe(III)-, Co(II)-, and Mn(III)-containing POMs have successfully been synthesized from a trivacant lacunary Keggin-type silicotungstate precursor TBA4H6[A-α-SiW9O34]·2H2O (TBA = tetra-n-butylammonium), and the highly distorted octahedral geometries of...

Pure and doped magnesium oxide nanoparticles were successfully synthesized employing a sol-gel process. The synthesized nanoparticles were characterized by thermal differential analysis, X-ray powder diffraction, transmission electron microscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometer. X-ray diffraction patterns confirmed the crysta...
متن کاملChiral salen-metal derivatives of polyoxometalates with asymmetric catalytic and photocatalytic activities.
Immobilization of the chiral salen-metal complex [Mn(III)(salen)(H(2)O)(2)ClO(4)] on the Keggin-type polyoxometalate (POM) skeletons leads to the isolation of POM derivatives functionalized with chiral salen-metal complexes, which represent the first examples of introducing chiral salen-metal complexes into the POM systems.
