Abstract

A new network structure compound constructed by hydrogen bonds and π-π stacking has been synthesized by the reaction of homophthalic acid with 4,4-bipyridine in the CH3OH/H2O (v:v = 1:1). It was characterized by elemental analysis and X-ray single crystal diffraction analysis. The crystal of the title complex belongs to monoclinic, space group P21 with a = 0.50711(10) nm, b = 2.0581(4) nm, c = 0.81465(16) nm, β = 105.24(3) º, V = 0.8203(3) nm3, Z = 2, Dc = 1.362 μg·m-3, μ = 0.097 mm-1, F(000) = 352, and final R1 = 0.0525, ｗR2 = 0.1379. The molecules are connected by hydrogen bonds and π-π stacking to form one dimensional chain structure. The interaction of 1D chains form 2D layered and 3D network structure.
