Title Molecule

In the title molecule, C23H18O3, the dihedral angle between the two naphthalene ring systems is 80.44 (4)°. The mean plane of the bridging carbonyl C—C(=O)—C group makes a torsion angle of −68.55 (17)° with the naphthalene system of the 2,7-dimethoxynaphthalene unit and a torsion angle of −9.01 (19)° with the naphthalene ring system of the naphthoyl group. In the crystal, a weak C—H...O hydrogen bond occurs between the carbonyl O atom and an H atom of the naphthalene ring in the 2,7-dimethoxynaphthalene unit of a symmetry-related molecule.

Guanidinium Cation

The asymmetric unit of the title salt, CH6N3+·C2H8N+·C10H6O6S22−, consists of one dimethylammonium cation, one guanidinium cation, and two half naphthalene-1,5-disulfonate anions, which lie on inversion centers. N—H...O hydrogen bonds link the cations and anions into layers parallel to theabplane. The layers have a sandwich-like structure, with the sulfonate groups and cations forming outer slices and the naphthalene ring systems inside.

Ring Motif

In the title compound, [SbBr(C10H7)2], the SbIIIatom has a distorted trigonal–pyramidal coordination geometry and the planes of the two naphthalene ring systems make a dihedral angle of 80.26 (18)°. An intramolecular C—H...Br hydrogen bond forms anS(5) ring motif. In the crystal, weak C—H...Br interactions link the molecules into helical chains along theb-axis direction.
