rac-Bis{[1-(9,9-dioxo-10H-phenothiazin-10-yl)-2-propyl]dimethylammonium} terephthalate trihydrate
The protonated dioxopromethazinium cation in the title racemic compound, 2C17H21N2O2S+·C8H4O4 2-·3H2O, forms an N - H⋯O hydrogen bond to the terephthalate dianion through the N atom that is not part of a fused ring. The dianion lies on a center of inversion, and the carboxylate O atoms are also acce...

| Summary: | The protonated dioxopromethazinium cation in the title racemic compound, 2C17H21N2O2S+·C8H4O4 2-·3H2O, forms an N - H⋯O hydrogen bond to the terephthalate dianion through the N atom that is not part of a fused ring. The dianion lies on a center of inversion, and the carboxylate O atoms are also acceptors for two water mol-ecules. One of the uncoordinated water mol-ecules lies on a twofold rotation axis. The hydrogen bonds give rise to a sheet structure. © International Union of Crystallography 2007. |
