A 1-D zigzag coordination polymer, {[Cu2(H2pztc)(ox)(bpy)2] · 8H2O}n (1) (H4pztc = pyrazine-2,3,5,6-tetracarboxylic acid, ox = oxalate, bpy = 2,2'-bipyridine), has been synthesized under hydrothermal conditions. X-ray single crystal diffraction analysis indicates that the structure of the complex belongs to triclinic system, P 1 space group with a = 9.6085(19) Å, b = 10.111(2) Å, c = 11.009(2) Å, α = 99.41(3)°, β = 102.87(3)°, γ = 114.55(3)°, V = 907.9(3) Å3, Z = 1. Cu(II) is six coordinate by H2pztc2-, bpy, and ox2-, the oxalate produced from decarboxylation of H4pztc. [Cu2(ox)(bpy)2(H2O)2(NO3)2] (2) was also obtained from filtrate after 1 separated.
