title: Memanti-nium chloride 0.1-hydrate.
abstract: The crystal structure of the title compound, C(12)H(22)N(+)·Cl(-)·0.1H(2)O, consists of (3,5-dimethyl-1-adamantyl)ammonium chloride (memanti-nium chloride) and uncoordinated water mol-ecules. The four six-membered rings of the memanti-nium cation assume typical chair conformations. The Cl(-) counter-anion links with the memanti-nium cation via N-H⋯Cl hydrogen bonding, forming channels where the disordered crystal water molecules are located. The O atom of the water mol-ecule is located on a threefold rotation axis, its two H atoms symmetrically distributed over six sites; the water mol-ecule links with the Cl(-) anions via O-H⋯Cl hydrogen bonding.
