ABSTRACT The title compound, 6C(13)H(24)N(+)·H(2)Si(8)O(20)(6-)·44H(2)O, belongs to the class of cyclosilicate hydrates, which structurally can be positioned between the zeosils and the clathrate hydrates. [Si(8)O(18)(OH)(2)] cubes carrying six negative charges are located on crystallographic inversion centres and are surrounded by six adamantyltrimethylammonium cations.
