One of the goals of chemistry is the molecular design of materials to achieve specific or multifunctional properties. Very successful approaches are molecular architecture and crystal engineering. Within these two fields, a combination of metal ions with organic ligands was shown to be very fruitful in building metal-organic frameworks (MOFs) that possess attractive space for functions such as chemisorption, gas storage, catalysis, magnetism, conductivity and luminescence properties. However, the rational design and preparation of MOFs for specific applications are still at an evolutionary stage. Therefore, much work is required to figure out the relevant structural types and to seek versatile ligands that are able to control structure for rational synthesis. In this study, Simultaneous use of the multidentate ligand H2tdpd and bridging ligand pyrazine and 4,4’-bipyridine for the reaction with cobalt(II) and zinc(II) ions affords three interesting hierarchical polymeric architectures: 1D ladder chain compound and two kinds of 1D chain compounds. These obtained structures show that the metal ions and the solvent molecules play important roles to construct coordination polymers.

化学的目标之一是材料的分子设计，以实现特定或多功能性能。非常成功的方法是分子体系结构和晶体工程。在这两个领域中，将金属离子与有机配体的组合结合在建造金属有机框架（MOF）中非常富有成果，该框架具有吸引人的空间，可用于化学吸附，储气，催化剂，磁性，电导率，电导率和发光特性。但是，对于特定应用的MOF的合理设计和制备仍处于进化阶段。因此，需要做很多工作才能找出相关的结构类型，并寻求能够控制理性综合结构的多功能配体。在这项研究中，与钴（II）和锌（II）离子的反应同时使用多耐配体H2TDPD和桥接配体吡嗪和4,4'-Bipyridine提供了三种有趣的层次结构结构：1D LADDER链链和两种1D链化合物的两种。这些获得的结构表明，金属离子和溶剂分子在构建协调聚合物中起着重要作用。
