A novel coordination polymer[Zn(N 3 ) 2 (bpp)] n [bpp =1,3-bis(4-pyridyl)-propane]was synthesized at room temperature and structurally chara cterized by means of X-ray single cry stal diffraction.The results show t hat the polymer exhibits a linear chain stru cture;the Zn-Zn distance is 12.235?.Each Zn?ion is coordinated by two nitrogen atoms from bpp ligands and t wo nitrogen atoms from azido(N 3- )groups,the coordination geometry o f Zn?ion is a slightly distorted tetrahed ron,the angles around Zn?ions are from 103.27°to 121.37°.In t he solid-state structure of the polyme r,the linear chains are stacked with parallel mode along a direction.Moreover,between adjacent chains,there areπ-πinteractions between pyridine rings,which are arranged in face-to-face fashion with interplanar distances of av.3.821?.CCDC:189591. 展开更多

针对广电系统双芯入户的解决方案,传统的单芯预制成端蝶形引入光缆组件具有一定的局限性,因此本文提出了一种双芯预制成端蝶形引入光缆组件,本文介绍了三种分支器构成的双芯预制成端蝶形引入光缆组件,概述了生产流程;剖析了各自优劣势。
关键词 引入光缆 预制成端组件 分支器
