提出了三种新的磺酸银金属有机骨架，并提出了一种面向后代的设计策略。[[Ag6(mesitylenetrisulfonate)2(H2O)5].2H2O]infinity(1)、[Ag4(十二烷基四磺酸)(H2O)2](无穷大)(2)和[[Ag4(1，3，5，7-tetrakis(4，4‘-sulfophenyl)adamantane)(H2O)2].1.3H2O]infinity(3)代表了一系列开放框架的银磺酸盐固体，其中有机连接物在确定整体结构中起着关键作用。化合物1形成柱状层状结构，而化合物2和3形成三维网状结构，该三维网状结构是由一维磺酸银柱的交联物形成的。这三种固体都含有水分子，可以去除水分子以产生稳定到300摄氏度以上的固体。粉末X射线衍射研究和蒸汽吸收实验表明，对于1和2，当客人被移除时，固体保持其结构，并且对于所有三种固体，水蒸气被固体以化学计量比吸收。提出了一种理想化的磺酸银骨架，并与已报道的结构进行了比较，提出了未来一维和可能的零维聚集体结构设计中的结构约束准则。
Three new silver sulfonate metal-organic frameworks are presented along with a design strategy for future generations. [[Ag6(mesitylenetrisulfonate)2(H2O)5].2H2O]infinity (1), [Ag4(durenetetrasulfonate)(H2O)2](infinity) (2), and [[Ag4(1,3,5,7-tetrakis(4,4'-sulfophenyl)adamantane)(H2O)2].1.3H2O]infinity (3) represent a series of open-framework silver sulfonate solids where the organic linker plays a key role in determining the overall structure. Compound 1 forms a pillared layered structure, while compounds 2 and 3 form 3-D nets derived from cross-linking of 1-D columns of silver sulfonates. All three solids incorporate water molecules, which can be removed to yield a solid stable to in excess of 300 degrees C. Powder X-ray diffraction studies and vapor sorption experiments show, for 1 and 2, that the solids retain their structure when guests are removed and, for all three, that water vapor is resorbed stoichiometrically by the solids. An idealized silver sulfonate framework is proposed, and upon comparison to the reported structures, guidelines are proposed for structural constraints in the design of future generations of 1-D and possibly 0-D aggregate structures.
