作为正在进行的合成新型柱撑层状材料的研究计划的一部分，将羟基乙酸镍和钴插入α-磷酸锆的胺插层之间。所得的镍复合材料的结构，来自X-射线粉末数据，被发现是由一个三层的镍原子桥接的羟基和乙酰基。加热到420 ℃将羟基乙酸层转化为氧化物，并赋予复合材料有序的磁畴。磷酸盐层似乎充当模板，指导这类复合材料中插入层的生长。
As part of an ongoing research program to synthesize novel pillared layered materials, nickel and cobalt hydroxyacetates were inserted between the layers of amine intercalates of α-zirconium phosphate. The structure of the resultant nickel composite, derived from x-ray powder data, was found to consist of a three-tiered layer of nickel atoms bridged by hydroxo and acetato groups. Heating to 420�C converted the hydroxyacetate layers to oxide and imparted ordered magnetic domains to the composite. The phosphate layers appear to act as a template directing the growth of the inserted layers in this class of composite materials.
