Bis(4-ethylanilinium) 4,5-Dichlorophthalate(1)

Abstract

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 inter-actions. Intra-molecular 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 carboxyl-ate groups and the anion aromatic ring plane are 13.72 (3) and 84.64 (3)°. © International Union of Crystallography 2007.
