研究了次氮基三乙酸酯插层镁铝层状双氢氧化物在硝酸镧溶液中的反应。 La3+通过形成螯合络合物并入中间层。 NO3- 也被用作电荷平衡阴离子。在螯合过程中，层间重复序列从 11.9 A 增加到 13.9 A。化学分析表明，在层间内形成了 1:1 和 1:2 金属：螯合物。含La3+的双氢氧化物的煅烧导致形成LaAlO3。
The reaction of a nitrilotriacetate-intercalated Mg-Al layered double hydroxide in a lanthanum nitrate solution is studied. La3+ is incorporated into the interlayer through the formation of a chelate complex. NO3- is also taken up as a charge-balancing anion. During chelation the interlayer repeat increases from 11.9 A to 13.9 A. Chemical analysis suggests that 1:1 and 1:2 metal:chelate complexes are formed within the interlayer. Calcination of the La3+-containing double hydroxide results in the formation of LaAlO3.
