This work presents first-principles calculations on the surface and defect impact upon zinc stannate (ZS) materials with perovskite bulk structures. The structure electronic properties of both a perfect 001 surfaces point ZS were investigated by means density functional theory calculations. cohesive energies those O, Sn, or Zn defects decreased compared that ZS. Oxygen formed more easily than o...

Doping at the possible A or B site in ABO3 perovskite can alter structural, morphological and optical properties of compounds. Perovskite alkaline earth stannate BaSnO3 doped with Fe resulted BaSn1-xFexO3 compounds having different concentrations (x = 0.00, 0.01, 0.02, 0.03, 0.05 0.07) were prepared by solid-state method. The Rietveld analyzes performed to determine phase purity changes structu...

The proton conductivity and structural properties of (1–x)CsH2PO4–xZnSnO3 composites with compositions x = 0.2–0.8 were studied. Zinc stannate ZnSnO3 was prepared by the thermal decomposition zinc hydroxostannate ZnSn(OH)6, which synthesized hydrolytic codeposition. To optimize microstructure ZnSnO3, products ZnSn(OH)6 characterized analysis X-ray diffraction, Fourier transform infrared spectro...

The isostructural title compounds, {(C7H7N2)2[SnI4]} n , (1), and {(C7H5F2N2)2[SnI4]} n , (2), show a layered perovskite-type structure composed of anionic {[SnI4](2-)} n sheets parallel to (100), which are decorated on both sides with templating benzimidazolium or 5,6-di-fluoro-benzimidazolium cations, respectively. These planar organic heterocycles mainly form N-H⋯I hydrogen bonds to the term...
