Dimethyl-ammonium 3-carb-oxy-benzoate.
The asymmetric unit of the title organic salt, C(2)H(8)N(+)·C(8)H(5)O(4) (-), consists of two dimethyl-ammonium cations and two 3-carb-oxy-benzoate anions. The 3-carb-oxy-benzoate anions are linked via strong inter-molecular and nearly symmetrical O-H⋯O hydrogen bonds forming infinite chains parallel to [111]. Neighbouring chains are further connected by the dimethyl-ammonium cations via N-H⋯O bonds, resulting in a double-chain-like structure. The dihedral angles of all carboxylate groups with respect to the phenylene rings are in the range 7.9 (1)-20.48 (9)°.
