Crystal structure, phase transitions and dielectric properties of a new layered bimetallic hydrogenselenite: [CuZnCl^sub 2^(H^sup 2^O)^sub 4^]·(HSeO^sub 3^)^sub 2

Crystal structure, phase transitions and dielectric properties of a new layered bimetallic hydrogenselenite: [CuZnCl^sub 2^(H^sup 2^O)^sub 4^]·(HSeO^sub 3^)^sub 2

This work investigates the synthesized way of the [CuZnCI2(H2O)4]·(HSeO3)2 compound. Single crystal X- ray diffraction showed that this new hydrogenselenite derivative was crystallized in the orthorhombic system with Pnma space group.

Zusammenfassung:This work investigates the synthesized way of the [CuZnCI2(H2O)4]·(HSeO3)2 compound. Single crystal X- ray diffraction showed that this new hydrogenselenite derivative was crystallized in the orthorhombic system with Pnma space group. A profound spectroscopic study was carried out using the Infrared and Raman techniques in order to prove the presence of bonds related to the selenite anion. TG/DTA analysis shows the presence of a phase transition at 580 K that was confirmed in the impedance and modulus measurements through the dielectric study.
