羧酸桥联双核铜配合物的合成与表征

Synthesis and Characterization of Binuclear Copper Complexes Bridged by Carboxyl Group

本文以金属铜粉为起始原料，利用氧化加成反应，合成了６个新的羧酸桥联双核铜配合物：［Ｃｕ（Ｃ６Ｈ５ＣＯＯ）２Ｌ］２［Ｌ＝２—氨基吡啶（１），２—甲基吡啶（２），２，４，６—三甲基吡啶（３），三苯基氧化膦（４），喹啉（６）］和配合物（５）［Ｃｕ２（Ｃ６Ｈ５ＣＯＯ）４（ｄｐｐｅ）］（ｄｐｐｅ＝Ｐｈ２ＰＣＨ２ＣＨ２ＰＰｈ２），通过元素分析、磁化率、红外光谱、分子量测定、电导测定对配合物进行了表征，并经四圆衍射方法测定了配合物４的晶体结构．

Six new binuclear copper complexes, [Cu(C 6H 5COO) 2·L] 2 (L=2-aminopyridine(1),2-methylpyridine(2),2,4,6-trimethylpyridine(3),triphenylphosphine oxide(4),quinoline(6) and [Cu 2(dppe)(C 6H 5COO) 4](5),have been synthesised by oxidative addition reaction. These complexes were characterized by elemental analysis, IR spectra, conductivity and magnetic diple moment, Molecular structure of the complex(4) has been determined by four cycle diffraction method.
