چکیده
The title compound, C(9)H(18)NO(2) (+)·NO(3) (-), is an anhydrous nitrate salt of gabapentin, which is formed serendipitously in the presence of selected non-coordinating metals. The crystal structure involves extensive hydrogen bonding between the -NH(3) (+) and -COOH groups and the nitrate anion.

As the title gabapentin complex, [Zn(4)(OH)(2)(NO(3))(2)(C(9)H(17)NO(2))(4)(H(2)O)(4)](NO(3))(4) is located about a centre of inversion, the asymmetric unit contains two disordered nitrate ions and half a complex mol-ecule. The two zinc ions have different coordination environments: one is slightly distorted octa-hedral and the other is trigonal-pyramidal. The conformation of the gabapentin mol...

In the crystal of the title salt, C3H11NOP(+)·NO3 (-), dicationic inversion dimers are head-to-tail connected by a pair of strong N-H⋯O hydrogen bonds. The resulting graph-set descriptor of this ring system is R 2 (2)(10). The nitrate counter-anions connect the dicationic dimers via N-H⋯O hydrogen bonds, forming two-dimensional networks in the bc plane.
