A three-dimensional hydrogen-bonded framework in 4,4'-trimethylenedipiperidinium-2,5-dicarboxybenzene-1,4-dicarboxylate-water (1/1/1).
The title compound is a salt, C13H28(N2)(2+).C10H4(O8)(2-).H2O. In the anion, there are two short intramolecular hydrogen bonds [O.O 2.395 (2) and 2.383 (2) A; O.H.O 175 and 172 degrees]. Pairs of anions and pairs of water molecules are linked by further O-H.O hydrogen bonds [O.O 2.756 (2) and 2.980 (2) A; O-H.O 171 and 175 degrees] into cyclic centrosymmetric R(6)(6)(16) aggregates; these aggregates are linked via the cations into a three-dimensional framework by means of four distinct N-H...O hydrogen bonds [N...O 2.787 (2)-3.204 (2) A; N-H...O 148-173 degrees].
