摘　　要：在热甲醇溶剂中以三苯基膦为还原剂直接与硝酸铜反应得到一价铜化合物[Cu(PPh3)2(NO3)]。通过熔点测定合成的配合物的纯度,实验值接近理论值。测定了配合物的红外光谱,分析结果表明配合物中除三苯基膦参加配体外,硝酸根作为双齿配位也参加配位。将配合物[Cu(PPh3)2(NO3)]溶解在有机溶剂乙酸中,用EDTA络合滴定确定了配合物中Cu元素的百分含量。In the hot methanol solvent,triphenylphosphine as the ligand and reducing agent directly react with cupric nitrate to get the copper compound.By measuring the melting point of the complex,the experimental value is close to the theoretical value.The IR spectra of complexes exhibit the expected bands due to the Ph3P ligand,the above results that NO3-is bidentate.The complex is dissolved in the organic solvent of acetic acid,and in the complex,complexometric titration with EDTA to divalent copper complexes have been confirmed in the percentage content of Cu element.
