چکیده
In the title molecular compound, C(4)H(12)NO(+)·C(8)H(5)O(4) (-), the N,N-dieth-yl(hy-droxy)ammonium cation (DTHA) is linked to the 3-carb-oxy-benzoate anion (HBDL) by O-H⋯O and N-H⋯O hydrogen bonds with a graph-set motif R(2) (2)(7). In the crystal, helical chains are formed by O-H⋯O hydrogen bonds, propagating along [010]. The crystal structure is further stabilized by π-π inter-actions between inversion-related HBDL benzene rings [centroid-centroid distance = 3.900 (4) Å] and C-H⋯O inter-actions.

In the centrosymmetric title compound, 2C(4)H(12)NO(+)·C(8)H(4)O(4) (2-), two N,N-dieth-yl(hy-droxy)ammonium cations are linked to a benzene-1,4-dicarboxyl-ate dianion by a combination of O-H⋯O and N-H⋯O hydrogen bonds, which can be described in graph-set terminology as R(2) (2)(7). The crystal structure is further stabilized by C-H⋯O hydrogen bonds, leading to the fomation of a ribbon-like net...
