The crystal structure of the title compound, 2C8H12N+·C8H3Cl2O4 2−, is stabilized by nine N—H...O and four C—H...O hydrogen bonds, and also by C—H...π interactions. Intramolecular C—H...O hydrogen bonds form C(6) chains along the c axis. This chain and the other hydrogen bonds generate edge-fused [R 1 2(6)R 1 2(4)R 4 3(10)R 1 2(4)R 3 2(9)] motifs in a three-dimensional network. The dihedral angles between the carboxylate anion and the cation aromatic ring planes are 75.90 (2) and 68.15 (2)°, and the dihedral angles between the carboxylate groups and the anion aromatic ring plane are 13.72 (3) and 84.64 (3)°.

Hydrogen Acceptor

The title compound lies about a crystallographic inversion centre located at the terephthalate moiety. The two peri-benzoylnaphthalene units having atrope chirality are also situated centrosymmetrically. In the two peri-benzoylnaphthalene moieties, two benzoyl groups are substituted at 1 and 8 carbons of the naphthalene ring in anti-orientation. Then two absolute configurations of peri-benzoylnaphthalene moieties are consequently assigned as complementary to each other, i.e., one unit has R,R-configuration and the other S,S-one, respectively. The two benzoyl groups in peri-benzoylnaphthalene moiety and the terephthalate phenylene ring are non-coplanarly located against the naphthalene ring. The dihedral angles of each benzene ring of two benzoyl groups and terephthalate unit with the naphthalene ring are 73.73 and 75.96, and 71.79°. In molecular packing, several kinds of weak interactions are responsible to induce three-dimensional molecular network. Especially, the synergetic effect realized through the bidentate hydrogen acceptor function in bidirectional C-H···π non-classical hydrogen bonds by the terephthalate phenylene ring moiety plausibly plays the determining role.
