title: 2-[3-(1H-Benzimidazol-2-yl)prop-yl]-1H-benzimidazol-3-ium 3,5-dicarb-oxy-benzoate-benzene-1,3,5-tricarb-oxy-lic acid-water (1/1/1).
abstract: The title compound, C(17)H(17)N(4) (+)·C(9)H(5)O(6) (-)·C(9)H(6)O(6)·H(2)O, contains a protonated 2,2'-(1,3-propanedi-yl)bis-(1H-benzimidazole) cation, a deprotonated benzene-1,3,5-tricarb-oxy-lic acid anion, a neutral benzene-1,3,5-tricarb-oxy-lic acid mol-ecule and a water mol-ecule, which are linked together through N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds into almost double sheets parallel to (4). These hydrogen-bonded sheets are packed in the crystal with the formation of centrosymmetric voids of 25.5 Å(3), which are filled by the water mol-ecules.
