Five-fold interpenetrating diamondlike 3D metal-organic frameworks constructed from the rigid 1,2-di(pyridin-4-yl)ethane-1,2-diol ligand and aromatic carboxylate

Two novel five-fold interpenetrating diamondlike 3D coordination polymers, namely [M(bpg)(bdc)·2H2O] (M = Zn(II), Cd(II)) have been synthesized by the hydrothermal reactions between M(NO3)2·6H2O(M = Zn(II), Cd(II)), meso-α,β-bi(4-pyridyl) glycol (bpg) and 1,4-benzenedicarboxylic acid (H2bdc). The two compounds were characterized by X-ray single crystal diffraction, infrared spectroscopy, elemental analysis, thermogravimetric analysis, and their fluorescence properties were also investigated.
