Solvothermal reactions of Zn(II) salts and 4-(1H-pyrazol-4-yl)pyridine (Hpypz) in the presence of monocarboxylate or dicarboxylate ligands produced two porous coordination polymers, namely, [Zn(pypz)(OAc)]·guest (1·g, HOAc = acetic acid) and [Zn2(pypz)2(oba)]·guest (2·g, H2oba = 4,4′-oxobisbenzoic acid). Single-crystal x-ray diffraction analyses showed that both 1 and 2 contain 2-fold interpenetrated three-dimensional nbo-a {Zn(pypz)}+ networks consisting of 3-connected Zn(II) ions and 3-connected pypz– ligands. After the carboxylate ligands were considered, 1 retains the nbo-a network structure and contains one-dimensional channels with very narrow apertures. However, 2 becomes a new uninodal 6-connected topol. (point symbol 33.42.56.64) and contains discrete pores. Powder x-ray diffraction showed that, after solvent removal, 1 undergoes obvious framework shrinkage, while 2 retains the original unit cell. Activated 1 and 2 both exclude N2 at 77 K, but readily adsorb CO2 at 195 K with unconventional isotherm shapes, indicating the different types of framework flexibilities.
