Abstract
Hydrothermal reactions of Zn(NO3)2·6H2O with 1,3-benzenedicarboxylic acid (1,3-H2BDC) and 1,4-bis[2-(4-pyridyl)ethenyl]benzene (1,4-bpeb) under pH = 2.5 or 8.0 gave rise to two coordination polymers {[Zn6(μ-OH2)(1,3-BDC)6(1,4-bpeb)4]·MeCN}n (1) and {[Zn8(1,3-BDC)8(1,4-bpeb)4]·2H2O}n (2). Both compounds were characterized by elemental analysis, IR, powder X-ray diffraction, and single-crystal X-ray diffraction. Compound 1 has two types of dinuclear zinc cores as nodes and displays an intriguing three-dimensional (3D) three-fold interpenetrating (4,6)-connected network with an unprecedented (3264)(3244687)2 topology. Compound 2 exhibits an unusual 3D two-fold interpenetrating pcu net with a Schlafli symbol 41263. The formation of 1 and 2 provided an interesting insight into the effect of pH values on the construction of coordination polymers under solvothermal conditions. Thermal stability and photoluminescence properties of 1 and 2 were also investigated.
