The organic cation of the title salt, C(17)H(12)N(4)O(2+)·2Cl(-)·H(2)O, is nearly planar, the dihedral angle between two pyridine rings being 2.53 (16)° and that between the pyridinum and furan rings being 4.17 (19)°. Mol-ecules are linked via N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds, forming a three-dimensional framework and π-π stacking inter-actions help to stabilize the crystal structure [the imidazole-pyridine and imidazole-benzene centroid-centroid distances are 3.501 (3) and 3.674 (3) Å; respectively].
