摘要

Hydrothermal reactions of Zn(NO3)2·6H2O with 1,2-di(4-pyridyl)ethylene (dpe) and 1,4-benzenedicarboxylate (1,4-BDC) or 1,3-benzenedicarboxylate (1,3-BDC) in water gave rise to two new metal-organic coordination poly-mers, [Zn(1,4-BDC)(dpe)]n (1) and [Zn4O(1,3-BDC)3(dpe)]n (2). Both compounds were characterized by elemental analysis and IR spectroscopy, and their structures were determined by single crystal X-ray diffraction. 1 displays a rare 5-fold interpenetrating 66-diamondoid framework while 2 possesses an interlocked 3D network formed by in-clined interpenetration of 2D (4,4) networks that are constructed by μ4-oxo tetrazinc Zn4O cores and the bridging dpe and 1,3-BDC ligands. Thermal and photoluminescent properties of 1 and 2 were also investigated.
