碱金属与脱水沸石Y和A的相互作用在与那些金属在非水液体溶剂中的溶解具有许多相似性的过程中导致包合物的形成，包合物可以被认为是紧密间隔的簇的有序阵列，并且其性质取决于簇之间的相互作用。电子自旋共振，磁化率和粉末中子衍射结果的综合分析，使我们能够详细地遵循背后的化学形成的钠和钾为基础的“簇晶体”分别在沸石Y和A。
The interaction of alkali metals with dehydrated zeolites Y and A leads, in a process which bears many similarities to the dissolution of those metals in non-aqueous liquid solvemts, to the formation of inclusion compounds which may be regarded as ordered arrays of closely spaced clusters, and whose properties are dependent on interactions between the clusters. A combined analysis of electron spin resonance, magnetic susceptibility and powder neutron diffraction results enabled us to follow in detail the chemistry behind the formation of sodium- and potassium-based ‘cluster crystals’ in zeolites Y and A respectively.
