Acridinium 3-carb­oxy­pyrazine-2-carboxyl­ate

The title ion pair, C(13)H(10)N(+)·C(6)H(3)N(2)O(4) (−), contains a protonated acridine cation and a 3-carb­oxy­pyrazine-2-carboxyl­ate monoanion, which are linked together through O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds. These hydrogen bonds generate a C(10) chain graph-set motif. The crystal st...

Sumario:The title ion pair, C(13)H(10)N(+)·C(6)H(3)N(2)O(4) (−), contains a protonated acridine cation and a 3-carb­oxy­pyrazine-2-carboxyl­ate monoanion, which are linked together through O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds. These hydrogen bonds generate a C(10) chain graph-set motif. The crystal structure is further stabilized by extensive π–π stacking inter­actions between nearly parallel [dihedral angle = 1.21(2)°] acridine systems. The shortest distance between the centroids of the six-membered rings within the cations is 3.6315 (8) Å. In addition, C—H⋯π edge-to-face inter­actions are present.
