A novel 2-D organic templated bismuth–oxygen compound (H2en)0.5[BiO(OH)2(H2O)] (1) (en = ethylenediamine) has been synthesized in the presence of ethylenediamine acting as a template under mild hydrothermal conditions. The structure was determined by single crystal X-ray diffraction and further characterized by IR spectrum, elemental analysis, scanning electron microscopy (SEM), photoluminescence and thermogravimetric analysis. In the compound, the Bi atom was coordinated by eight oxygen atoms. The BiO8 polyhedra share edges or corners with their neighbors to result in an anionic inorganic layer with protonated ethylenediamine cations occupied between layers. At ambient temperature, 1 shows a blue emission band which may be assigned to the 1P11S0 transitions of the s2 electron of the Bi3 + ion. To our knowledge, 1 is the first example of layered bismuthate templated by an organic amine.  相似文献

A novel coordination compound [Zn(DAT)2(H2O)4](PA)2⋅2H2O has been synthesized using 1,5‐diaminotetrazole (DAT) as ligands. It crystallizes in the monoclinic space group C2/c, with a=1.51973(19) nm, b=0.67904(9) nm, c=3.0712(4) nm, β=90.507(2)°, V=3.1692(7) nm3, Z=4, and μ=0.888 mm−1. With the intermolecular hydrogen bonds, molecules are linked together to form a three‐dimensional net structure. Thermal decomposition mechanism of the title compound was predicted based on DSC, TG‐DTG, and FT‐IR analyses. The kinetic parameters of the first exothermic process of the title compound were studied applying the Kissinger's and Ozawa–Doyle's methods.  相似文献

The first nanoflower lead(II) coordination compound, [Pb(pcih)N3MeOH] n (1), (“pcih” is the abbreviations of 2-pyridinecarbaldehyde isonicotinoylhy-drazoneate) were synthesized by a sonochemical method. The new nano-structure was characterized by transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction, elemental analyses and IR spectroscopy. Single crystalline material was obtained using a heat gradient applied to a solution of the reagents. Compound 1 was structurally characterized by single crystal X-ray diffraction. The determination of the structure by single crystal X-ray crystallography showed that the complex taking the form of a zig-zag one dimensional polymer in the solid state and the coordination number of PbII ions is six, (PbN4O2), with three N-donor and one O-donor atoms from two “pcih” and one O-donors from methanol and one N atom from terminal azide anion. It has an asymmetrical coordination sphere. The supramolecular features in these complexes are guided and controlled by weak directional intermolecular interactions. The chains interact with each other through π–π stacking interactions creating a 3D framework. After thermolysis of 1 at 180 °C with oleic acid, pure phase nano-sized lead(II) oxide was produced. The morphology and size of the prepared PbO samples were further observed using SEM.  相似文献
