Based on the building block of 2-phenyl-4,6-di(pyridin-2-yl)pyrimidine (L=C₂₀H₁₄N₄), a Cu(Ⅰ) polymer [(CuC₂₀H₁₄N₄)(CuCl₂)]_∞ and a salt with H₂SO₄ [(C₂₀H₁₆N₄)(HSO₄)₂] have been synthesized by hydrothermal method and characterized by X-ray single-crystal diffraction. In the Cu(Ⅰ) polymer, although the central metal ions of Cu(Ⅰ) directly coordinate with the building block L, they still do not assembly expected grid-type complexes and there exists a one-dimensional chain constructed through coordinate bonds. In the salt, hydrogen bonds along with two kinds of π…π supramoleuclar interactions fabricate two-dimensional (2D) networks which further generate a 3D supramolecular architecture via interlayer π…π interactions. Fluorescent spectra show that the L emits blue fluorescence and its Cu(Ⅰ) polymer and salt decrease the fluorescent intensity.
