In this paper, the synthesis of Ca0.1Na0.9Ti0.1Nb0.9O3 (CNTN) ceramic by a solid-state reaction is reported. The results of Rietveld refinement of X-ray diffraction patterns at room temperature showed a pure tetragonal perovskite (P4mm space group).

The new organic-inorganic compound tetrapropylammonium tetrabromozincate [N(C 3 H 7 ) 4 ] 2 ZnBr 4 has been synthesized and characterized by single-crystal X-ray diffraction, differential scanning calorimetry, IR, Raman and impedance measurements. The crystal structure refinement shows that the [N(C 3 H 7 ) 4 ] 2 ZnBr 4 compound is crystallized in the monoclinic system (space group C 2/c ) with the following unit cell parameters: a = 33.145(5) Å , b = 14.234(3) Å , c = 15.081(2) Å , b = 110.207(5)°and Z = 8. The structural arrangement of the title compound can be described as an alternation of organic and inorganic layers along the [100] direction. Differential scanning calorimetry disclosed two order-disorder transition phases located at 340 and 393 K. Besides, an analysis of the dielectric constants e 0 and e 00 , at several frequencies, shows a distribution of relaxation times. This relaxation is probably due to the reorientational dynamics of alkyl chains.
