【摘要】 以草酰氯乙酯和2,4,6-三甲基苯胺为原料,合成了N-2,4,6三甲基苯基草胺酸乙酯,然后用硝酸铜与N-2,4,6三甲基苯基草胺酸乙酯在弱酸性条件下,制备了铜的一维链状配合物[Cu（2,4,6-tmpa）₂]_n（1）（2,4,6-tmpa为N-2,4,6-三甲基苯基草胺酸根离子）,并对其进行了元素分析、X-射线单晶结构分析和变温磁化率表征.晶体结构表明,配合物1的中心原子Cu（Ⅱ）处于五配位四方锥构型的配位环境中,通过羧基氧反式桥连形成1个一维链结构.变温磁化率分析表明,配合物1中铜（Ⅱ）离子间存在弱的铁磁相互作用,最佳拟合值为J=0.043 cm^-1,g=2.15.更多还原

【Abstract】 N-2,4,6-trimethylphenloxamate was synthesized by ethyl oxalyl monochloride and 2,4,6-trimethyaniline.Then Cu（NO₃）₂ is employed to react with N-2,4,6- trimethylphenloxamate to prepare the one-dimensional chain of[Cu（2,4,6-tmpa）₂]_?（1）.Complex 1 is characterized by elemental analysis,X-ray crystal structure analysis and variable temperature magnetic measurements.X-ray crystal structure analysis shows that Cu（Ⅱ） ion lies in a distorted tetragonal pyramid geometry（five-coordinated） and a one-dimensional chain structure is formed by the carboxylic bridges.Weak ferromagnetic interaction is operating between Cu（Ⅱ） ions in the chain and the best fitting to the experimental data gives J = 0.043 cm^-1,g=2.15.更多还原
