摘　　要：合成了六种稀土苯氧乙酸的二元、三元配合物,其通式为RE(POA)3、RE(POA)3Phen、RE(POA)2hq(RE=L a、Y;HPOA=苯氧乙酸;Phen=邻菲罗啉;Hhq=8-羟基喹啉)。研究了配合物在不同溶剂中的溶解性及摩尔导电性,用IR、UV、DTA等方法研究配合物的结构特点,并对L a(POA)3对植物铅、镉污染的影响做了初步的探讨。AbSix new solid rare earth complexes with phenozyacetic acid were synthesized. The general formulas for these complexes are RE（POA）3,RE（POA）3 Phen,RE（POA）2 hq（RE=La,Y;HPOA=phenoxyacetic acid;Phen：1,10-phenanthroline ;Hhq=Hydroxyquinoline）. The solubility and molar conductance of these complexes were studied and the structure were investigated by IR ,UV,DTA. The studies also show that La（POA）3 had effect on plant Pb ,Cd pollution.
