rac-2-Amino­pyridinium cis-2-carb­oxy­cyclo­hexane-1-carboxyl­ate

In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (−), the cis anions associate through head-to-tail carb­oxy­lic acid–carboxyl O—H⋯O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter­linked through the carboxyl groups, forming cyclic R (2) (2)(8...

Descripción
Sumario:In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (−), the cis anions associate through head-to-tail carb­oxy­lic acid–carboxyl O—H⋯O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter­linked through the carboxyl groups, forming cyclic R (2) (2)(8) associations with the pyridinium and an amine H-atom donor of the cation. Further amine–carboxyl N—H⋯O inter­actions form enlarged centrosymmetric rings [graph set R (4) (4)(18)] and extensions down b, giving a three-dimensional structure.
