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

Abstract Two new selenite SrZn 2 (SeO 3 ) 3 (1) and SrZn 0.68 Cu 0.32 (SeO 3 ) 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 1 ¯ triclinic space group. However, compound (2) was crystallized in P2 1 /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.
