МОНОМЕРНЫЙ КОМПЛЕКСНЫЙ АНИОН [HfF5(H2O)2]– В КРИСТАЛЛИЧЕСКОЙ СТРУКТУРЕ ТРИГИДРАТА ПЕНТАФТОРОГАФНАТА 4-АМИНО-1,2,4-ТРИАЗОЛИЯ: СИНТЕЗ И РЕНТГЕНОСТРУКТУРНОЕ ИССЛЕДОВАНИЕ, STRUCTURAL CHARACTERIZATION OF DICYANIDOBIS(N,N?-DIMETHYLTHIOUREA-kS)CADMIUM(II), ...

The single crystal X-ray data show an infi. 741 – 745 nite three-dimensional structure formed by the hydrogen bonding and — stacking interactions. <...> The CdO nanoparticles are obtained by direct calcination at 400 ēC, 500 ēC and 600 ēC in the air atmosphere as well as by thermolysis in oleic acid at 200 ēC. The obtained cadmium(II) oxide nanoparticles are characterized by X-ray diffraction and scanning electron microscopy. <...> This study demonstrates another potential application of cadmium(II) supramolecular compounds in the preparation of nanoscale cadmium(II) oxide materials with a specific size and morphologies. <...> In this paper, we report a new three-dimensional supramolecular compound [Cd(4-pyc)2(H2O)4]n (1). <...> This compound was used as a precursor for the Payehghadr M., Morsali A., 2013 742 M. PAYEHGHADR, A. MORSALI preparation of cadmium(II) oxide nanoparticles. <...> Two different methods were described for the synthesis of cadmium(II) oxide nanoparticles: direct calcination at three different temperatures and decomposition in oleic acid of compound 1. <...> The molecular structure plot and the simulated XRD powder pattern based on single crystal data were prepared using the Mercury software [ 22 ]. <...> Synthesis of cadmium(II) oxide nanoparticles by direct calcination of compound 1. <...> Nanostructures of CdO have been generated by the thermal decomposition of compound 1. <...> The final product upon the calcination of compound 1 at three different temperatures, based on their IR and XRD patterns, is CdO in all three cases. <...> Synthesis of cadmium(II) oxide nanoparticles by thermal decomposition in oleic acid as a surfactant. <...> RESULTS AND DISCUSSION A reaction between 4-pyridine carboxylic acid (4-Hpyc) with cadmium(II) chloride leads to the formation of a new 3D Cd(II) supramolecular compound [Cd(4-pyc)2(H2O)4]n (1). <...> The crystal data for 1 indicate a triclinic space group P1 (Tables 1 and 2). <...> Single crystal XRD analysis of compound 1 reveals that Cd(II) atoms are coordinated by water molecules and 4-pyridine carboxylate ligands resulting in a six-coordinate complex. <...> V, Е3 Z Density (calculated), gŒcm–3 Absorption coefficient, mm–1 Crystal size, mm range for data collection <...>
