摘要

Two new coordination polymers, {[Zn₃L_2.5(渭₃-OH)(H₂O)₃]路4H₂O}_n (1) and [Zn₂L_1.5(渭₃-OH)(4,4鈥?bpy)_0.5]_n (2) (H₂L = 2,5-bis(4-methylbenzoyl)terephthalic acid, 4,4鈥?bpy = 4,4鈥?bipyridine), have been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, TG, PXRD and single crystal X-ray diffraction. Complex 1 possesses a 2D double-layer configuration with 4⁸路6² network constructed with trinuclear zinc(II) clusters and L^{2鈭?/sup> ligands, which extends into a 3D architecture via O-H路路路O interactions between coordinated water molecules and lattice water molecules. Complex 2 is a uninodal 8-connected 3D framework with a 424路64 network based on tetranuclear zinc(II) clusters as nodes. Moreover, the luminescent properties of complexes 1 and 2 were also investigated.}
