چکیده
A 4-aza-1-azoniabicyclo-[2.2.2]octane cation, a 2-amino-benzoate anion and a neutral 2-amino-benzoic acid mol-ecule 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 intra-molecular N-H⋯O hydrogen bond occurs in the anion and in the neutral 2-amino-benzoic acid mol-ecule. The cation provides a charge-assisted N-H⋯O hydrogen bond to the anion, and the 2-amino-benzoic acid mol-ecule 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-carboxyl-ate N-H⋯O hydrogen bonds. N-H⋯N hydrogen bonds are also observed.

In the title compound, C(8)H(14)N(3) (+)·BF(4) (-)·H(2)O, the cation, anion and water molecule all lie on mirror planes. The BF(4) (-) anion is disordered over two orientations with occupancies refined to 0.57 (2) and 0.43 (2). The water mol-ecule is linked to the cation via an O-H⋯N hydrogen bond. Weak inter-molecular O-H⋯F, C-H⋯O and C-H⋯F hydrogen bonds consolidate the crystal packing.
