The newly synthesized complexes have been characterized by elemental analyses, TGA, spectroscopic techniques (FT-IR and UV–Vis), conductance, magnetic susceptibility studies. Single-crystal X-ray
摘要研究了在不同氮配体存在下2-氯-4-氟苯甲酸酯和2,4-二氯苯甲酸酯配体对铜离子的配位行为。四种新的铜(II)配合物,[反式-Cu(2-Cl-4-FC7H3O2)2(β-pic)2] 1,1,[反式-Cu(en)2(H2O)2](2-Cl-4 -FC7H3O2)2,2,[反式Cu(2,4-Cl2C7H3O2)2(β-pic)2(H2O)2],3和[反式Cu(en)2(H2O)2](2,4 -Cl2C7H3O2)2·2H2O,4,(其中β-pic=β-甲基吡啶,en =乙二胺)是通过将β-甲基吡啶/乙二胺添加到分别悬浮在甲醇-水中的水合芳基羧酸铜(II)中而合成的(4: 1)在室温下混合。新合成的复合物已通过元素分析,TGA,光谱技术(FT-IR和UV-Vis),电导,磁化率研究进行了表征。配合物的单晶X射线结构测定表明配合物1和3中存在中性结构,而配合物2和4具有由配合物阳离子[trans-Cu(en)2(H2O)2]
