摘　　要：用N－（膦酸甲基）甘氨酸与醋酸铜在强酸性和煮沸条件下，合成了铜（Ⅱ）与N－（膦酸甲基）甘氨酸的配合物．经红外光谱、紫外光谱、热谱、磁化率等表征，并用凝固点降低法测定了分子量．结果表明，该配合物是由两个水分子和两个N-（膦酸甲基）甘氨酸中的两个氮原子与铜（Ⅱ）形成的配合物，其化学式为：［Cu（OOCCH2NHCH2PO3H2）2·（H2O）2］·H2O．The complex copper with N-(phosphonomethyl) glycine has been synthesized at high acidity and boiling. It was studied with IR, visible and UV absorption spectra, thermal analysis and magnetic susceptibility. The molecular weight was measured by lowering the freezing point method. It is proved that the coordination number of the complex is four, which is composed of two N from N-(phosphonomethyl) glycine groups and two water molecules. The chendcal formula is [Cu (OOCCH2NHCH2PO3H2)2·(H2O)2]·H2O.
