In the title salt, [C(6)H(5)N(CH(3))(3)][Sn(2)Br(5)(C(7)H(6)Br)(4)], the Sn(IV) atoms of the dinuclear anion are bridged by a Br atom; the Sn-Br(bridge) bond lengths are 2.9818 (5) and 3.0470 (5) Å. Both Sn atoms show a distorted cis-trigonal-bipyramidal coordination geometry that is distorted towards a square pyramid. In the crystal, weak C-H⋯π inter-actions occur between anions and cations.

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...

Introduction Orthorexia is a neuotic behavior characterized by an obsession with healthy eating. This trend growing among medical students; it may be related to the stress experienced these young people. Objectives The aim of this study was determine prevalence orthorexic eating behaviors students in Tunisia and examine relationship perceived stress. Methods Our descriptive analytical cross-sec...

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...
