Abstract

A new lithium zinc iodate, LiZnO(IO₃), has been prepared by hydrothermal reactions at 200 C. Single-crystal X-ray diffraction experiment revealed that the compound crystallizes in a noncentrosymmetric orthorhombic space group Ama2 with cell parameters: a = 6.3386(6) Å, b = 11.2613(11) Å, c = 4.6840(5) Å, Z = 4. In the structure, the basic building units are the distorted ZnO₆ octahedron, LiO₄ tetrahedron and the IO₃ group. These groups are linked together to form a three-dimensional structure by sharing the oxygen atoms. The DSC measurement demonstrates that the compound is stable up to 490 C. Powder second-harmonic generation (SHG) test shows that the SHG effect is about 2 × KH ₂PO₄.
