A proton transfer compound (2a4mpH)2(btcH2) was obtained by the reaction of benzene-1,2,4,5-tetracarboxylic acid (btcH4) with 2-amino-4-methyl pyridine (2a4mp), 1:1 mole ratio and is characterized by IR spectroscopy and single crystal X-ray diffraction analysis. The ion pair is crystallized in monoclinic system and P21/c space group with following cell parameters: a = 11.321(2) Å, b = 13.553(2)...
In this research N(2-chloro-phenyl)4-nitro-thiobenzamide as a ligand was synthesized. One mmol of mercury oxide was added to the solution of 1 mmol ligand in 45 ml chloroform and after 90 min the mixture through celite or BaS to remove unreacted mercury(II) compounds. The yellow crystals, which formed by slow evaporization, was separated and recrystallized from chloroform as fine yellow crystal...
The new trans-[Pt(4-mpy)2Cl4] (1) complex (4-mpy is 4-methylpyridine) was prepared from the reaction of H2PtCl6.6H2O with 4-methylpyridine in methanol. Synthesized complex was thoroughly characterized by elemental analysis, IR and 1H-NMR spectroscopy.Elemental analysis data (C, H, N) support the general composition of the title complex and the structure have been established by single-crystal X...
In this paper, Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) thin films were deposited on single crystal SrTiO3 (STO) (100) by pulsed laser deposition (PLD) technique at different pressures of oxygen. Crystal structure of bulk and thin film samples was studied by x-ray diffraction (XRD). The XRD results indicate that both bulk and thin film samples have cubic structures. AFM micrographs showed an increase i...
ZnO nanorods array films were coated on a glass template through a two-step chemical process. First, a sol-gel spin coating method was used to produce a ZnO seed layer and after that, the ZnO nanorods arrays were grown on it through a low temperature aqueous method. Synthesized films were studied by scanning electron microscope (SEM) and X-ray diffractometer (XRD). X-ray diffraction results sho...
the reaction of barium chloride with 2, 6-pyridinedicarboxylic acid in water led to the formation of a novelpolymeric complex formulated as {[ba2(hpydc)2(pydc)(h20)3].h20.(h2pydc)}.(i). the crystal structure of (i)was characterized by single crystal x-ray diffraction method. the complex was crystallized in the monoclinicsystem with space group p2/c, with four molecule in unit-cell, e.g z=4. the...
