A new lithium zinc iodate, LiZnO(IO3), has been prepared by hydrothermal reactions at 200 C. Singlecrystal X-ray diffraction experiment revealed that the compound crystallizes in a noncentrosymmetric orthorhombic.space group Ama2 with cell parameters: a = 6.3386(6) angstrom, b = 11.2613(11) angstrom, c = 4.6840(5) angstrom, Z = 4. In the structure, the basic building units are the distorted ZnO6 octahedron, LiO4 tetrahedron and the 103 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 degrees C. Powder second-harmonic generation (SHG) test shows that the SHG effect is about 2 x KH2PO4.
