摘　　要：A new copper（1）-lead（Ⅱ） oxyhalide, CuPb2（OH）2Cl3, has been prepared by hydrothermal reaction and structurally characterized by single-crystal X-ray analysis. The compound crystallizes in tetragonal, space group 14（1）/acd with a = b = 13.77（1）, c = 15.38（1） A, V = 2916.2（2）, Z = 4, Mr = 618.29, Dc = 5.633 g/cm^3,μ = 49.97（2） mm^-1, F（000） = 4192, the final R = 0.0204 and wR = 0.0452 for 757 observed reflections with I 〉 2σ（I）. The structure of CuPb2（OH）2Cl3 contains one-dimensional helical chains built by CuCl4 tetrahedra with comer-sharing along the c-axis, in which the Pb^2＋ and OH^- ions are located at the voids between chains. Optical reflectance spectrum measurements indicate that it is a semiconductor with a band-gap of 3.23 eV.A new copper（1）-lead（Ⅱ） oxyhalide, CuPb2（OH）2Cl3, has been prepared by hydrothermal reaction and structurally characterized by single-crystal X-ray analysis.
