چکیده
Iron- and nickel-substituted decaniobates, [H2Fe(III)Nb9O28](6-) and [H3Ni(II)Nb9O(28)](6-) were hydrothermally synthesized as tetramethylammonium salts and the structures were determined by X-ray crystallography. The highly soluble title compounds were characterized by ESI-MS, FT-IR and UV-Vis titration.

Here we report synthesis and characterization of early transition-metal(TM)-substituted decaniobates as a continuation of our previous report of tetramethylammonium (TMA) salt of FeNb9 and NiNb9: TMA6[H2Cr(III)Nb9O28]·14H2O (1, CrNb9), TMA8[Mn(III)Nb9O28]·29H2O (2, MnNb9) and TMA7[H2Co(II)Nb9O28]·25H2O (3, CoNb9). Among the TM-substituted decaniobates, CoNb9 or NiNb9 exhibit a higher photocatal...
متن کاملNickel ferrite as a recyclable nanocatalyst for synthesis of novel highly substituted 1,4-dihydropyrano[2,3-c]pyrazole derivatives
Highly substituted 1,4-dihydropyrano[2,3-c]pyrazole derivatives were synthesized by four-component reaction of aromatic aldehydes, malononitrile, ethyl acetoacetate and various phenylhydrazine, using nickel ferrite as a recyclable nanocatalyst by a grinding method under solvent-free and thermal conditions. The reaction has the advantages of good yields, less pollution, ease of separation of the...
متن کاملFacile synthesis of 5-substituted-1H-tetrazoles catalyzed by reusable nickel zirconium phosphate nanocatalyst
5-Substituted-1H-tetrazoles were synthesized by the [3 + 2] cycloaddition of sodium azide with various nitriles in the presence of nickel zirconium phosphate (NiZrP) as an effective heterogeneous catalyst in dimethylsulfoxide at 120 °C. This method has the advantages of good to high yields, simple methodology and easy work-up. The catalyst can be recovered by centrifuging and reused with good y...

Fungus-plant associations are of the most important mutually beneficial relationships in the ecosystem which positive effects on growth, physiology and ecology of different plants have been already demonstrated. Biological methods such as employing symbiotic (arbuscular mycorrhizal) fungi to roots of plants are considered as potential effective ways of reducing the stressful effects of soil con...
