摘　　要：在乙醇介质中用水合氯化稀土与4-(2-吡啶偶氮)-间苯二酚(PAR)和1,10-二氮杂菲(Phen)作用,合成了十二个未见报道的固体配合物,[RE(PAR)_2Phen]Cl·3H_2O(RE=Y,Nd-Lu)。通过元素分析、化学分析、红外光谱、电子光谱、核磁共振氢谱、差热-热重分析和摩尔电导测定等方法确定了配合物的组成,研究了有关的物理和化学性质。The complexes, [RE(PAR)_2phen]Cl. 3H_2O(where RE=Y, Nd-Lu; PAR=4-(2-Pyridylaro)tesorcinol: Phen=Phenanthroline) have been synthesized by the reaction of PAR, Phen and hydrousrare earth chlorides in ethanol and characterised by elemental analyses, NMR, IR and UV spectro-scope, molar conductance, thermogravimetry(TG) and differential thermal analyses (DTA). The re-sults show that the rare earth ion is coordinated by four nitrogen atoms, two oxygen atoms belongingto two mo ecu es of PAR, and the other two nitrogen atoms belonging to one molecule of Phen. Thecoordination number of rare earth ion is eight.
