摘　　要：在水-乙醇混合体系中，1，2-环己二胺四乙酸、氨基乙酸分别与聚吡唑硼酸钾在室温下反应，用盐酸调pH值7-8，形成以羧酸中氧原子和氨基中的氮原子为配位点的配位聚合物[K（C14H18N2O8）·CH3OH·H2O]。（1）和[K（NH2CH2COO）（NH2CH2COOH）]n（2）．用元素分析，红外光谱等进行了表征，并用X-ray测定了配位聚合物的晶体结构．Reactions of 1,2-diaminocyclohexane tetraacetic acid and glycine with tripyrazolylborate potassium and VOS04, at room temperature in the system of EtOH/H2O with the pH≈7-8 adjusted by solution of HCI, respectively result in two coordinated polymers, which are[K （C14H18N2O8）·CH3OH·H2O]n（1） and [K（C2H4NO2）2]n（2）,with the oxygen atom of acetate anions and nitrogen atom of amido as the coordination sites. The two coordinated polymers have been characterized by IR and elemental analysis. And their crystal structures were determined by X-ray diffraction.
