title: Diacridinium hexa-chloridoplatinate(IV) dihydrate.
abstract: The asymmetric unit of the title compound, (C(13)H(10)N)(2)[PtCl(6)]·2H(2)O, contains a protonated acridine cation, one half of a [PtCl(6)](2-) dianionic complex and a solvent water mol-ecule. The octa-hedral [PtCl(6)](2-) dianion is located on an inversion centre. π-π inter-actions between neighboring acridinium cations produce stacks along the a axis; the shortest distance between the centroids of the six-membered rings within the cations is 3.553 (9) Å. In the crystal, two independent inter-molecular O-H⋯Cl hydrogen bonds, both involving the same Cl atom of the anion as acceptor, give rise to chains also running along the a axis; in addition each water mol-ecule, as a hydrogen-bond acceptor, is linked to the acridinium N-H group.
