Abstract: The asymmetric unit of the title compound, C₁₇H₁₇N₂O₂⁺·Cl^-·H₂O, contains one-half of the cation, one-half of a water molecule and a chloride anion. The complete cation is generated by crystallographic two-fold symmetry, with one C atom lying on the rotation axis. The O and Cl atoms have site symmetry 2. The imidazolidium ring is oriented at a dihedral angle of 4.15 (3)° with respect to the 4-methoxyphenyl ring and an intramolecular C-HO interaction occurs. In the crystal structure, intermolecular O-HCl and C-HCl hydrogen bonds link the molecules. There is a - contact between the imidazolidium and 4-methoxyphenyl rings [centroid-to-centroid distance = 3.625(3 Å]. There is also a C-H contact between the methyl group and the 4-methoxyphenyl ring.
