报道了N ,N′ 双 (2 羟基苯基 )草酸二酰胺 (简称H4hpox)与稀土元素 3种类型 8个配合物的合成 ,经IR、UV、摩尔电导、元素分析、TG DTA等方法对配合物进行了表征。确定了这些配合物的组成为 :(1)M2 L(OH) 2 ·2H2 O(M =La3 + ,Gd3 + ) ;(2 )M3 L2 ·nH2 O(M =Nd3 + ,Er3 + ,Yb3 + ) ;(3)ML(OH) (H2 O)·nH2 O(M=Sm3 + ,Tm3 + ,Lu3 + )。并推测出可能的结构
The synthesis of eight complexes of N, N ’bis (2-hydroxyphenyl) oxalic acid diamide (H4hpox) and rare earth elements was reported. The complexation of these complexes with IR, UV, molar conductance, elemental analysis and TG DTA The material was characterized. The composition of these complexes was determined to be: (1) M2 L (OH) 2 · 2H 2 O (M = La3 +, Gd3 +); (2) M3 L2 · nH2 O (3) ML (OH) (H 2 O) · nH 2 O (M = Sm 3+ , Tm 3+ , Yb 3+ Lu3 + ). And guess the possible structure
