Abstract

Five new coordination polymers, namely, [Zn(1,3-BDC)(1,4-bpetmb)]n (1), {[Zn2(5-Cl-1,3-BDC)2(1,4-bpetmb)2]·MeCN}n (2), [Zn(5-NO2-1,3-BDC)(1,4-bpetmb)0.5]n (3), {[Zn(5-NH2-1,3-BDC)(1,4-bpetmb)0.5]·2H2O}n (4) and [Zn2(μ-OH)(1,3,5-BTC)(1,4-bpetmb)]n (5) have been synthesized under solvothermal conditions, based on the bis-pyridyl linker 1,4-bis[2-(4-pyridyl)ethenyl]-2,3,5,6-tetramethylbenzene (1,4-bpetmb) along with 1,3-benzenedicarboxylate (1,3-BDC) or its derivatives such as 5-chloro-1,3-benzenedicarboxylate (5-Cl-1,3-BDC), 5-nitro-1,3-benzenedicarboxylate (5-NO2-1,3-BDC), 5-amino-1,3-benzenedicarboxylate (5-NH2-1,3-BDC) and 1,3,5-benzenetricarboxylate (1,3,5-BTC). Compounds 1–5 have been characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction (PXRD) and unambiguously by single crystal X-ray diffraction analysis. 1 and 2 feature the 2D (4,4) net. 3 comprises an interlocked 3D framework, and the 3D framework is derived from the inclined interpenetration of the 2D (4,4) net. 4 exhibits a thick 2D (3,4)-connected network with a Schläfli symbol of (63)(65·8). 5 displays a 3D two-fold interpenetrating (3,5)-connected framework with the Schläfli symbol of (63)(67·83). Thermal stability and solid-state photoluminescence properties of 1–5 were also investigated.
