Two polyoxometalate assemblies, TBA(9)[{γ-H(2)SiW(10)O(36)Al(2)(μ-OH)(2)(μ-OH)}(3)] (1; TBA = tetra-n-butylammonium) and TBA(6)Li(3)[{γ-H(2)SiW(10)O(36)Al(2)(μ-OH)(2)(μ-OH)}(3)]·18H(2)O (2), were synthesized by trimerization of a dialuminum-substituted silicotungstate monomer. Both 1 and 2 possessed a layered structure composed of a basal sheet unit TBA(3){γ-H(2)SiW(10)O(36)Al(2)(μ-OH)(2)(μ-OH)}(3) and interlayer cations. The interconversion between 1 and 2 reversibly took place through interlayer cation exchange.
两种多金属氧酸盐组装体,TBA([{γ-H(2)SiW(10)O(36)Al(2)(μ-OH)(2)(μ-OH)}(3)](1;TBA=四正丁基铵)和 TBA(6)Li(3)[{γ-H(2)SiW(10)O(36)Al(2)(μ-OH)(2)(μ-OH)}(3)]·18H(2)O(2),是通过三聚单体的二铝取代硅钨酸盐合成的。1 和 2 均具有由基底片单元TBA(3){γ-H(2)SiW(10)O(36)Al(2)(μ-OH)(2)(μ-OH)}(3)和层间阳离子组成的层状结构。1 和 2 之间的相互转化通过层间阳离子交换可逆进行。
