Abstract
One new compound, [Ag(p-bix)]3[Ag(Hbtc)2]·2H2O (H3btc=1,2,4-benzenetricarboxylate, p-bix=1,4-bis(imidazol-1-ylmethyl)-benzene), has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, PXRD, luminescent analysis, and single-crystal X-ray diffraction. X-ray structural analysis revealed that 0-D unit [Ag(Hbtc)2]3− and two kinds of 1-D linear chain [Ag(p-bix)]∞+, can be found within the crystal structure. The combination of 0-D [Ag(Hbtc)2]3− unit and 1-D undulated chain [Ag1(p1-bix)]∞+ through weak Ag–O bond gave rise to 2-D anionic supramolecular doublelayer. Then the grids of the 2-D layer are threaded by 1-D linear cationic chain [Ag2(p2-bix)]∞+ to generate entangled 3-D architecture with unusual poly(pseudo-rotaxane)-type arrangements. Luminescent properties of the title complex were also studied in this paper.
