Several hydrazinium (1 +) and dihydrazinium salts of aliphatic and aromatic carboxylic acids have been prepared by neutralisation of these acids with hydrazine hydrate in aqueous medium. They are hydrazinium hydrogendicarboxylates of malonic, succinic, glutaric and adipic acids, hydrazinium hydr...detailed

The first hydrazinium-bearing zeolite-like compound, (N2H5)3Ge7O15(OH)·2.5H2O, has been synthesized by low-temperature hydrazine-induced hydrolysis of fluorogermanic acid, H2GeF6. The crystal structure of hydrazinium germanate has been solved by direct methods and refined by the Rietveld method...detailed

The hydrazinium cations N2H62+/N2H5+ form ion pairs with [Pt(CN)4]2−. Outer-sphere charge transfer excitation (PtII → N2H62+/N2H5+) induces an oxidative addition: N2H62+/N2H5+Pt(CN)42- → [PtIV(CN)4(NH3)2] and [Pt(CN)4(NH3)(NH2)], respectively.detailed

Species including N2H4, NH3 and N2O are known to be present near the surface of burning hydrazinium nitroformate (HNF). In this paper, planar laser induced fluorescence from the near surface region of burning HNF pellets is reported indicating the presence of NO2. These four species are formed i...detailed

Hydrazinium hydrogendicarboxylates of pimelic, suberic, azelaic, sebacic, tartaric, α-ketoglutaric and iminodiacetic acids and dihydrazinium dicarboxylates of malic, aspartic and glutamic acids have been prepared by accomplishing neutralisation of aqueous hydrazine hydrate with the respective a...detailed

A series of new metal hydrazido-oxalates with the formula [M(Hox)2(H2O)2]·nH2O, where M = Co (1), Ni (2) and Zn (3); Hox = hydazido-oxalate; n = 0 (Co), 1 (Ni) and 5 (Zn), as well as (N2H6)0.5[Cd(Hox)2]NO3 (4) and the hydrazinium uranyl oxalate (N2H6)[(UO2)2(C2O4)3]·2H2O (5) were synthesized. ...detailed

In the present work, the UV absorption spectra of seven complexes of hydrazinium 5-aminotetrazolate (HY-5AT), in the range of 4–12 eV, were calculated in both gas and water. The UV absorption spectra of the selected HY-5AT complexes were also calculated in the absence of the intermolecular inte...detailed

Several studies in the literature have investigated the electrochemical effects of oxalic acid and hydrazine on various materials in neutral (pH buffered to 7), basic or weakly acidic media (pH 6). The present work proposes electrochemical techniques that allow for the study of the electrochemic...detailed

A disposable electrochemical sensor was developed for convenient detection of gaseous formaldehyde. The sensor is composed of a three-electrode screen printed system modified with hydrazinium polyacrylate which was synthesised to serve a dual purpose, i.e. as formaldehyde accumulation/derivatisa...detailed
