摘　　要：在ｐＨ＝３．８酸性条件下合成了３－苯基偶氮－５－磺基水杨酸与Ｎｄ（Ⅲ）的酸式络合物，在弱碱性条件下合成了该染料与Ｎｄ（Ⅲ）的羟式络合物及Ｃｕ（Ⅱ）的络合物，对这些络合物进行了元素分析、热重分析，并测定了电导和红外光谱，确定了分子式，讨论了可能的配位环境．Ｎｄ（Ⅲ）的络合物中羧酸根均以二齿形式配位，偶氮基皆未参与配位，羧式络合物中酚基则参与配位．在Ｃｕ（Ⅱ）的络合物中，羧酸根以二齿形式配位，酚基，偶氮基也同时参与了配位．The acid complex of 3 phenylazo 5 sulfo salicylic with Nd(Ⅲ) has been synthesised at pH 3 8 acid condition. Under weak basic condition, the hydroxyl complex of this dye with Nd(Ⅲ) and its complex with Cu(Ⅱ) have been synthesised. These complex compounds have been characterized by elementary analysis, thermogravimetric analysis,molar conductance, IR spectra. The molecular formulas have been determined. The coordination environments of these metal ions have been discussed. In both complexes of Nd(Ⅲ) the carboxylates were bidentate, but azo group were not coordinated to Nd(Ⅲ). In hydroxyl complex, the phenolic group was coordinated. In Cu(Ⅱ) complex of PASSA, the azo group, the phenolic group and the carboxylate were all coordinated and the carboxylate was bidentate.
