摘要
合成了3 羧基水杨醛缩甘氨酸Schiff碱的双核铜、三核铜和异三核铜锌配合物.用元素分析,红外光谱、紫外可见光谱对配合物的组成和结构进行了表征.磁性测定表明,三核铜配合物的铜离子之间存在着较强的反铁磁性自旋交换相互作用,而在双核铜和异三核铜锌配合物中,由于距离较远,两个铜离子之间基本上没有磁性相互作用.
3-Carboxylsalicylidene glycine(H_(3)GS) and its complexes Na_(2)Cu_(2)(GS)_(2) ·2H_(2)O,Cu_(3)(GS)_(2) ·5H_(2)O,ZnCu_(2)(GS)_(2) ·5H_(2)O were synthesized and characterized with elemental analysis,IR and UV-vis spectroscopy.Magnetic measurement shows that there exists a strong antiferromagnetic spin exchange interaction in Cu_(3)(GS)_(2) ·5H_(2)O,while there is none spin exchange interaction in Na_(2)Cu_(2)(GS)_(2) ·2H_(2)O and ZnCu_(2)(GS)_(2) ·5H_(2)O due to the long distance between the Cu^(2+) ions.
