Tetramethylammonium hemi(terephthalate) dihydrate

Tetramethylammonium hemi(terephthalate) dihydrate

In the title compound, (CH3)4N+·0.5C8H4O42−·2H2O, the complete terephthalate dianion is completed by twofold symmetry and has a dihedral angle of 23.5 (2)° between the carboxylate group and its parent ring. Two independent water mole...
