| 摘 要： | The title complex [Cr2（8-hqn）2Cl4（H2O）2]·2（CH3）2CO （8-hqn = 8-hydroxyoxyquinolate） has been synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in the triclinic system, space group P^-1 with a = 8.719（1）, b = 9.226（1）, c = 9.717（1） A^°, α = 71.916（2）, β= 78.072（2）, γ = 76.014（2）°, V= 713.72（15） A^°^3, Z= 1, Dc= 1.597g/cm^3, F（000） = 350 and μ（MoKa） = 1.177 mm^-1, the final R = 0.0490 and wR = 0.1055 for 1616 observed reflections with I 〉 2σ（I）. It is a dimer constructed by two monomeric units [Cr（8-hqn）Cl2（H2O）] bridged by phenoxide-like oxygen atom from 8-hydroxyoxyquinolate, where the two six-coordinated Cr（Ⅲ）atoms exhibit an octahedral coordination geometry.
