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. 235A. 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. 821A. CCDC: 189591.
