1,1’-二氢-5,5’-联四唑-铅配位聚合物及其制备方法
摘要：
本发明公开了一种配位聚合物及其制备方法，配位聚合物晶胞中含有一个1,1’-二氢-5,5’-联四唑配体，一个铅(II)离子和三个配位水分子。制备步骤为：将1,1’-二氢-5,5’-联四唑与铅盐溶于溶剂中，过滤，加热至60～160℃，维持2～48小时，以每小时1～10℃的速率降温至10～40℃，析出无色晶体，抽滤，晾干，得到配位聚合物。本发明所制备的配位聚合物具有较高的氮含量，可作为单质炸药或固体推进剂燃速调节剂。
摘要（英）：

The invention discloses a coordination polymer and a preparation method thereof. A unit cell of the coordination polymer contains a 1,1'-dihydro-5,5'-bistetrazole ligand, a lead (II) ion and three coordinated water molecules. The preparation method comprises the following steps: dissolving 1,1'-dihydro-5,5'-bistetrazole and lead salt in a solvent, filtering the solution, heating the solid to 60-160 DEG C, maintaining the temperature for 2-48 hours, reducing the temperature to 10-40 DEG C at a rate of 1-10 DEG C per hour, precipitating a colorless crystal and carrying out suction filtration and airing, thus obtaining the coordination polymer. The prepared coordination polymer has higher nitrogen content and can serve as a single-compound explosive or solid propellant burning rate modifier.
