Summary, etc. <p style="text-align: justify;">A hydrogen bonded microporous network with Lewis basic N sites, viz<em>.</em>, {[Zn(TZ-HIP)(HPYTZ)(H2O)2]·3H<sub>2</sub>O}<sub>n<strong> </strong></sub>[TZ-HIP = 5-(tetrazol-5-yl)isophthalic acid, HPYTZ = 3,5-di(4-pyridyl)-1H-1,2,4- triazolate ligand] has been obtained from the dual ligand system of polydentate N-heterocyclic carboxylate and dipyridyl-type ligands. Single crystal X-ray diffraction analysis shows that the adjacent Zn(II) centers are bridged by HTZ-H<sub>2</sub>IP ligand to form 1D chain with HPYTZ molecules as free lateral arms. The paralleled chains are connected by H-bonding interactions to produce the 3D microporous network with 1D pores. It is interesting that the uncoordinated N atoms (Lewis base sites) pores cause Pb<sup>2+</sup> ions to produce a remarkably enhancing effect on the luminescent intensity of the zinc complex with high sensitivity in the detection range of 10<sup>-3</sup>-10<sup>-5</sup>mol L<sup>-1</sup> concentration limit. This coordination polymer may be used as a sensing material for developing a highly selective and sensitive Pb<sup>2+</sup> sensor in the biological and environmental materials.</p><p> </p>
