Metal iodates containing IO₃ polyhedra in asymmetric coordination environment due to the stereochemically active lone pairs can be used as useful optical materials in a wide transparent spectral range. In this research, we have synthesized a new europium iodate by a hydrothermal reaction using Na₂CO₃, Eu(NO₃)₃∙6H₂O, HIO₃, and water as reagents. The crystal structure of the europium iodate compound was determined using single crystal X-ray diffraction. The title compound crystallizes in the rhombohedral space group, R3c (No. 146), and consists of EuO₈, IO₃, and Na⁺ ions. A complete characterization including the energy dispersive X-ray spectroscopy (EDS), infrared, UV-vis diffuse-reflectance spectroscopy, thermogravimetric analysis (TGA) and second harmonic generation (SHG) will be presented.
