Controllable assembly of a three-dimensional metal-organic supramolecular framework including π-π stacking...

The mixed-ligand metal-organic complex poly[(μ(3)-phthalato)[μ(2)-3-(pyridin-2-yl)-1H-pyrazol-1-ido]dicopper(II)], [Cu(2)(C(8)H(4)O(4))(C(8)H(6)N(3))(2)](n), has been synthesized by the reaction of copper(II) acetate with 2-(1H-pyrazol-3-yl)pyridine (HL) and phthalic acid. The binuclear chelating-bridging L units are further linked by bridging phthalate ligands into a two-dimensional network parallel to the (010) plane. The two-dimensional networks are extended into a three-dimensional supramolecular architecture via π-π stacking interactions.
