4-Aza-1-azoniabicyclo­[2.2.2]octa­ne–2-amino­benzoate–2-amino­benzoic acid (1/1/1)

A 4-aza-1-azoniabicyclo­[2.2.2]octane cation, a 2-amino­benzoate anion and a neutral 2-amino­benzoic acid mol­ecule comprise the asymmetric unit of the title compound, C(6)H(13)N(2) (+)·C(7)H(6)NO(2) (−)·C(7)H(7)NO(2). An intra­molecular N—H⋯O hydrogen bond occurs in the anion and in the neutral 2-a...

Sumario:A 4-aza-1-azoniabicyclo­[2.2.2]octane cation, a 2-amino­benzoate anion and a neutral 2-amino­benzoic acid mol­ecule comprise the asymmetric unit of the title compound, C(6)H(13)N(2) (+)·C(7)H(6)NO(2) (−)·C(7)H(7)NO(2). An intra­molecular N—H⋯O hydrogen bond occurs in the anion and in the neutral 2-amino­benzoic acid mol­ecule. The cation provides a charge-assisted N—H⋯O hydrogen bond to the anion, and the 2-amino­benzoic acid mol­ecule forms an O—H⋯N hydrogen bond to the unprotonated amino N atom in the cation. In this way, a three-component aggregate is formed. These are connected into a three-dimensional network by amino–carboxyl­ate N—H⋯O hydrogen bonds. N—H⋯N hydrogen bonds are also observed.
