The acid adducts hydrazinium 2-hydroxybenzoate–2-hydroxybenzoic acid (1/1) and hydrazinium 3-hydroxy-2-naphthoate–3-hydroxy-2-naphthoic acid (1/1)

Abstract

The title molecular salts, N(2)H(5)(+)·C(7)H(5)O(3)(-)·C(7)H(6)O(3) and N(2)H(5)(+)·C(11)H(7)O(3)(-)·C(11)H(8)O(3), are acid adducts containing a hydrazinium cation, one molecule of a deprotonated acid and one molecule of a neutral acid. The two compounds contain essentially identical hydrogen-bond networks between the hydrazinium cation and the acid molecules, which define closely comparable two-dimensional layers in the structures. The planes of the aromatic rings within both structures are approximately parallel and the layers are stacked with comparable intermolecular interactions.

Template Free Anisotropically Grown Gold Nanocluster Based Electrochemical Immunosensor for Ultralow Detection of Cardiac Troponin I

“…The indium tin oxide glass (ITO) substrate of 1.5 cm × 1 cm size was cleaned thoroughly before use and air dried. Then, the ITO substrate was dipped in 10% HCl solution for about 10 min followed by annealing at the temperature ranges of 450–500 °C for 7 h and suddenly cooled to normal room temperature [ 15 , 25 ].…”

Design and synergistic effect of nano-sized epoxy-NiCo2O4nanocomposites for anticorrosion applications

“…The two characteristic vibrations of the M-O linkage of the Ni-Co metal complex were observed at 461 cm À1 and 504 cm À1 , conrming the presence of two metal components in the complex. [20][21][22][23][24] The two characteristic intense peaks at the lower frequency of 450 cm À1 and 502 cm À1 are attributed to the Ni-O and Co-O stretching vibrations in the metal oxide, and the double peaks at 1510 cm À1 and 1603 cm À1 are assigned to the characteristic nickel-cobalt oxide spinel composition formation. The wide peak at 3411 cm À1 conrms the presence of hydroxy groups, which may be due to physically adsorbed water molecules.…”
