摘　　要：[Pb（TPT）（μ-I）2PbI2（μ-I）2Pb（TPT）] 1 （TPT is the abbreviation of 3,5,6-tris（2- pyridyl）-1,2,4-triazine ligand） has been synthesized and characterized by elemental analysis, IR, J H- NMR spectroscopy and studied by thermal and electrochemical properties as well as X-ray crystallography. The single-crystal X-ray data show two different kinds of Pb2＋ ions in 1 with coordination numbers of six, Pbl = PbI6, and five, Pb2 = PbN312, with holodirected and hemidirected coordination spheres, respectively. The supramolecular features in 1 are negotiated through the weak but directional Pb...I, C-H...N and C-H...I interactions and aromatic π-π stacking interactions.[Pb（TPT）（μ-I）2PbI2（μ-I）2Pb（TPT）] 1 （TPT is the abbreviation of 3,5,6-tris（2- pyridyl）-1,2,4-triazine ligand） has been synthesized and characterized by elemental analysis, IR, J H- NMR spectroscopy and studied by thermal and electrochemical properties as well as X-ray crystallography.
