Abstract :

A new noncentrosymmtric europium iodate has been synthesized through a hydrothermal reaction using Na2CO3, Eu(NO3)�6H2O, HIO3, and water as reagents. The crystal structure of the newly synthesized iodate was determined by single-crystal X-ray diffraction. The material crystallizes in the rhombohedral space group, R3c (No. 161) with the unit cell parameters of a = b = 21.968(4) �� and c = 13.363(3) ��. The iodate material reveals three-dimensional framework consisting of EuO8, IO3, and IO4 polyhedra. The IO3 and IO4 polyhedra are in asymmetric coordination environment due to the stereochemically active lone pairs.Full characterization including energy dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), second-harmonic generation (SHG) measurements, infrared, and UV�vis diffuse� reflectance spectroscopy are also presented.
