Mild hydrothermal synthesis of the two compounds (SrZn2 (SeO3)‎ 3)‎ and (SrZn0.68Cu0.32 (SeO3)‎ 2)‎ : structural characterization, spectroscopic and magnetic studies

الملخص EN

Two new selenite SrZn2(SeO3)3 (1) and SrZn0.68Cu0.32(SeO3)2 (2) were synthesized by the hydrothermal technique under autogeneous pressure.

The crystal structure of both compounds was solved from X-ray diffraction data.

Compound (1) was crystallized in P triclinic space group.

However, compound (2) was crystallized in P21/n monoclinic space group.

Infrared studies confirm the presence of all vibration bands in both structures.

The temperature dependence of the magnetic susceptibility was measured in the temperature range of 10–300 K at different magnetic field intensities for both compounds.

No magnetic properties were detected for compound (1).

Mean while, compound (2) displayed antiferromagnetic properties.
