合成标题化合物［（ｓｅｄａ）Ｃｕ］·ＥｔＯＨ，并得到单晶［ｓｅｄａ＝Ｎ，Ｎ′－二水杨叉基－１，２－二－（４－甲氧基苯基）乙二胺］．Ｘ－衍射结构分析表明，晶体属正交晶系，空间群Ｐｂｃａ，晶体学数据：ａ＝２．０１１５（４）ｎｍ，ｂ＝１．３１９６（３）ｎｍ，ｃ＝２．１０５７（４）ｎｍ，晶胞体积Ｖ＝５．５８９（３）ｎｍ３，分子量５８８．１６，Ｚ＝８，Ｄｘ＝１．３９８ｇ／ｃｍ３，μ＝８．２３９ｃｍ－１，Ｆ（０００）＝２４６５，最终偏离因子Ｒ＝０．０７９，Ｒｗ＝０．０８３，（Δ／σ）ｍａｘ＝０．６８．结构分析表明，配体中二个偶氮甲碱中氮原子和二个酚氧原子与中心Ｃｕ原子配位，形成规则的菱形平面结构．

The title compound [(seda)Cu]·EtOH was obtained by the reaction of seda with hydrated copper chloride in ethanol acetone mixture. The crystal belongs to the orthorhombic space group Pbca with parameters:a=2.0115(4)nm,b=1.3196(3)nm,c=2.1057(4)nm,V=5.589(3)nm 3, Mr=588.16, Z=8,D x=1.398g/cm 3,μ=8.239cm -1 ,F(000)=2465,R=0.079,R w=0.083,(Δ/σ) max =0.68. The result reveals that copper ion is coordinated by two nitrogen atoms of azomethene and two phenoxy atoms of the ligand. The coordination geometry around the Cu(Ⅱ) is close to rhombic plane.
