一种新的有机-无机混配配位聚合物[Zn(N3)2(bpp)]n的自组装及晶体结构(bpp=1，3-二吡啶丙烷)

A novel coordination polymer [Zn(N₃)₂(bpp)]_n[bpp=1，3-bis(4-pyridyl)-propane] was synthesized at room temperature and structurally characterized by means of X-ray single crystal diffraction. The results show that the polymer exhibits a linear chain structure; the Zn-Zn distance is 12.235?. Each Zn(Ⅱ) ion is coordinated by two nitrogen atoms from bpp ligands and two nitrogen atoms from azido (N₃^-) groups， the coordination geometry of Zn(Ⅱ) ion is a slightly distorted tetrahedron， the angles around Zn(Ⅱ) ions are from 103.27° to 121.37°. In the solid-state structure of the polymer， the linear chains are stacked with parallel mode along a direction. Moreover， between adjacent chains， there are π-π interactions between pyridine rings， which are arranged in face-to-face fashion with interplanar distances of av. 3.821?. CCDC： 189591.
