meso-5,5,7,12,12,14-hexamethyl-1,4-diaza-8,11-diazoniacyclotetradecane bis(2-naphthoate) ethanol disolvate: centrosymmetric five-component aggregates linked into sheets by C-H...pi(arene) hydrogen bonding.

The title compound is an ethanol-solvated salt, C(16)H(38)N(4)(2+) x -2C(11)H(7)O(2)(-) x -2C(2)H(6)O, in which the cation lies across a centre of inversion in P2(1)/c. The ions are linked by N-H...O hydrogen bonds [H...O = 1.70 and 2.30 A, N...O = 2.624 (2) and 3.136 (2) A, and N-H...O = 178 and 151 degrees ], and the ethanol molecule is linked to the anion by an O-H...O hydrogen bond [H...O = 1.90 A, O...O = 2.728 (2) A and O-H...O = 171 degrees ], to form a centrosymmetric five-component aggregate. C-H...O hydrogen bonds and aromatic pi-pi-stacking interactions are absent, but the aggregates are linked into sheets by a single C-H...pi(arene) hydrogen bond.
