%X The crystal structure of the title compound, C12H22N+¡¤Cl ¡¤0.1H2O, consists of (3,5-dimethyl-1-adamantyl)ammonium chloride (memantinium chloride) and uncoordinated water molecules. The four six-membered rings of the memantinium cation assume typical chair conformations. The Cl  counter-anion links with the memantinium cation via N¡ªH...Cl hydrogen bonding, forming channels where the disordered crystal water molecules are located. The O atom of the water molecule is located on a threefold rotation axis, its two H atoms symmetrically distributed over six sites; the water molecule links with the Cl  anions via O¡ªH...Cl hydrogen bonding.
