Tartrate and succinate anions have been intercalated in Zn(3)Al and Zn(2)Cr LDHs. The preparations using either coprecipitation, anion exchange, or reconstruction methods are described. In the case of tartrate-containing LDH, coprecipitation and reconstruction methods have proved to be very limited to lead to pure materials due to the particular reactivity of tartrate anions. Intercalation of both anions under room-temperature conditions gives rise to expanded LDH with similar basal spacing. Moderate thermal treatments lead in all cases to a reorientation of the anions in the interlayer domains associated with an interlayer contraction occurring around 80 degrees C. The structural characterization, the thermal evolution, and the chemical stability of all the phases are studied by PXRD, FTIR, TGA, and DTA.
酒石酸盐和琥珀酸盐阴离子已插入到Zn(3)Al和Zn(2)Cr层状双氢氧化物（LDHs）中。文中描述了采用共沉淀法、阴离子交换法或重构法的制备过程。对于含酒石酸盐的LDH，由于酒石酸盐阴离子的特殊反应性，共沉淀法和重构法被证明很难得到纯物质。在室温条件下插入这两种阴离子会使LDH层间距增大。适度的热处理在所有情况下都会导致阴离子在层间域重新定向，同时在80℃左右会发生层间收缩。通过粉末X射线衍射（PXRD）、傅里叶变换红外光谱（FTIR）、热重分析（TGA）和差热分析（DTA）研究了所有相的结构特征、热演化过程和化学稳定性。
