The compound (H3IDC)(Prz)0.5(H2O) (H3IDC = imidazole-4,5-dicarboxylate, Prz = piperazine) has been prepared from a hydrothermal approach and was characterized by IR analysis and X-ray diffraction. Its crystal structure consists of discrete 4,5-imidazole-dicarboxylate, H2O and piperazine molecules. The whole structural motif was assembled by three different non-covalent interactions of O-H···O, N-H···O and π-π stacking, which play an important role in packing the molecules. Interestingly, the connections between imidazole-4,5-dicarboxylate molecule and water molecule result in a helical polymeric chain. Crystal data for compound 1: monoclinic system, space group P21/c, a = 6.4600(13), b = 19.910(4), c = 6.9123(14) , β = 94.26(3)°, V = 886.6(3) 3, Z = 4, C7H10O5N3, Mr = 216.18.
