摘要
A Zn（Ⅱ） coordination polymer [Zn（NIP）（3,3＇-bpt）].H20 （1, NIP = 5-nitroisophtha- late, 3,3＂-bpt = 1H-3,5-bis（3-pyridyl）-l,2,4-triazolate） has been synthesized by the hydrothermal reaction at 140 ℃ and structurally characterized by IR spectroscopy, X-ray diffraction, thermal analysis, single-crystal X-ray diffraction and luminescent properties. In complex 1, the zinc atom is five-coordinated with three carboxylate oxygen atoms from three H2NIP and two nitrogen atoms from two 3,3＇-bpt, respectively, forming a distorted trigonal bipyramidal geometry and showing a 1D chain structure, which is further bridged by NIP to form a 3D supramolecular network via self-assembly of hydrogen bonds.
