| Popis: | In the trication of the title hydrated molecular salt, C28H40N3O3+·3Cl−·2H2O, the central heterocyclic ring adopts a sofa conformation, with the exocyclic N—C bond in an equatorial orientation. The dihedral angles between the planar part of this heterocyclic ring and the two almost flat side-chain fragments, which include the aromatic ring and bridging atoms, are 28.8 (1) and 41.1 (1)°. Both diethylazaniumyl substituents have a tetrahedral geometry, while the dihedral angles between the above-mentioned flat part of the aryl fragments and the imaginary planes drawn through atoms C—N—C of the diethylazaniumyl substituents are 86.3 (2) and 80.4 (1)°, respectively. In the crystal, N—H...Cl hydrogen bonds link the cations and anions into [100] chains. The chains are cross-linked by numerous C—H...O and C—H...Cl interactions, generating a three-dimensional network. One of the chloride ions is disordered over two adjacent positions in a 0.895 (4):0.105 (4) ratio. |
