合成并表征了以[M（tdpd）2（L）2]2-（H2 tdpd = 1，4，5，6-tetrahydro-5，6-dioxo-2，3-pyrazinedicarbonitrile，L=solvent）和类三聚氰胺阳离子为配体的新型三氢键超结构.使用含有来自[M（tdpd）2（L）2]2-的两个AAA组的阴离子与含有一个DDD组（A=氢键受体，D=氢键供体）的阳离子一起导致在固态下形成互补的三重氢键键合模块。在所有情况下，构建模块通过额外的氢键相互作用进一步延伸以产生带，并且带被组装成片材。这些结果表明，氢键模块由不同类型的积木，其中之一是一个金属配合物，其中包括氢键受体网站和其他氢键供体分子，将是有吸引力的构建含金属的超分子系统的自组装技术。
Novel triply hydrogen bonded suprastructures based on [M(tdpd)2(L)2]2- (H2tdpd=1,4,5,6-tetrahydro-5,6-dioxo-2,3-pyrazinedicarbonitrile, L=solvent) and melamine-analogous cations have been synthesized and characterized. The use of anions containing two AAA sets from [M(tdpd)2(L)2]2- together with cations containing one DDD set (A=hydrogen-bond acceptor, D=hydrogen-bond donor) leads to the formation of complementary triply hydrogen bonded modules in the solid state. In all cases, the building module is further extended via additional hydrogen-bonding interactions to produce a tape, and tapes are assembled into sheets. These results show that a hydrogen-bonded module consisting of different kinds of building blocks, one of which is a metal complex that includes hydrogen-bond acceptor sites and the other is a hydrogen-bond donor molecule, will be attractive for constructing metal-containing supramolecular systems by the self-assembly technique.
