摘　　要：The title complex l-[Cult4（Hvap）z（vap）2（MeOH）2]（Cl04）2 1 has been synthesized and characterized by EA, IR, TGA, solid-state CD spectra and X-ray single-crystal analyses （I-H2vap： a Schiff base ligand derived from the condensation of o-vanillin and l-2-amino-3-phenyl-l-propanol）. Complex I crystallizes in monoclinic system, chiral space group P21 with a=10.4257（18）, b=21.695（4）, c=15.721（3）,A β = 94.443（3）°, V= 3545.1（11） A3, Z = 2, Cu4C7oH78N4022CI2, Mr = 1652.42, Dc = 1.548 g/cm3, F（0 0 0） = 1704 and μ（MoKα） = 1.338 mm-1. The final R = 0.0682 and wR = 0.1420 for 6170 observed reflections with I 〉 2if（l） and R = 0.1775 and wR = 0.1830 for all data. The structure of complex I contains a boat-shaped {Cu404} motif. The solid-state CD spectra confirm the chiral nature of complex 1.The title complex l-[Cult4（Hvap）z（vap）2（MeOH）2]（Cl04）2 1 has been synthesized and characterized by EA, IR, TGA, solid-state CD spectra and X-ray single-crystal analyses （I-H2vap： a Schiff base ligand derived from the condensation of o-vanillin and l-2-amino-3-phenyl-l-propanol）.
