Three structurally similar antipyrine derivatives of o-hydroxybenzylideneaminoantipyrine (o-HBAP), m-hydroxybenzylideneaminoantipyrine (m-HBAP) and p-hydroxybenzylideneaminoantipyrine (p-HBAP) were characterized by FT-IR, FT-Raman experimental techniques and density functional theoretical (DFT) calculations. The comparisons between the calculated and(More)
The title compounds, C10H10N(2)(2+).C8Cl4O(4)(2-).2H2O, (I), and 2C12H9N2+.C8Cl4O(4)(2-).C8H2Cl4O4.3H2O, (II), both crystallize as charge-transfer organic salts with the dianionic or neutral acid components lying on inversion centres. The acid and base subunits in (I) arrange alternately to generate a linear tape motif via N-H...O hydrogen bonds; these(More)
The asymmetric unit of the title compound, C(12)H(14)N(4)·C(8)H(6)O(4)·4H(2)O, consists of one half of the 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) mol-ecule, one half of the terephthalic acid (TA) mol-ecule and two water mol-ecules. Both the bib and the TA mol-ecules reside on crystallographic inversion centers, which coincide with the centroids(More)
In the cation of the title compound, [Mn(C(11)H(13)N(5))(2)](ClO(4))(2)·CH(3)CN, the metal atom is located on a twofold rotation axis and is six-coordinated by six N atoms from two different 2,6-bis-(4,5-dihydro-1H-imidazol-2-yl)pyridine (bip) ligands in a distorted octahedral geometry. The O atoms of the perchlorate anions are disordered with occupancies(More)
The NiO nanoparticles with the size of 9-30 nm were prepared by solid state method using nickel acetate and sodium hydroxide as the raw materials, and Tween 80 as the dispersant. The structure, morphology, size, and infrared and UV-Vis spectra were characterized by XRD, TEM, FTIR and UV-Vis, respectively. The XRD and TEM revealed that the products are(More)
This work deals with the IR and Raman spectroscopy of 4-(2-furanylmethyleneamino) antipyrine (FAP), 4-benzylideneaminoantipyrine (BAP) and 4-cinnamilideneaminoantipyrine (CAP) by means of experimental and quantum chemical calculations. The equilibrium geometries, harmonic frequencies, infrared intensities and Raman scattering activities were calculated by(More)
In the present study, bismuth sulfide (Bi2S3) nanoribbons were prepared by the hydrothermal method using bismuth nitrate (Bi(NO3)3 x 5H2O), thioacetamide (C2H5NS) and nitrilotriacetic acid (C6H9NO6) as raw materials at 180 degrees C for 12 h. The reaction time was largely reduced and the route has been unreported. The constituent, structure and morphology(More)
Steric hindrance layer can be established when the surfaces of nano-Al2O3 were grafted with polyacetal, which increased the dispersibility of the nano-particles as well as the compatibility between the particles and the resin matrix. Examination of X-ray photoelectron spectroscopy (XPS) demonstrated that the peak of Al(2p) on polyacetal grafted Al2O3(More)
The surface organic modification of attapulgite with silane coupling reagent was studied by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Qrgano-attapulgite/nylon 6 composites with different content of attapulgite were prepared by means of melt blending, and the crystal structure and morphology were investigated.(More)
