Cyclo-hexane-1,2-diammonium bis-(pyridine-2-carboxyl-ate).

ABSTRACT: In the dication of the title salt, C(6)H(16)N(2) (2+)·2C(6)H(4)NO(2) (-), the two ammonium groups are in the equatorial positions of the chair-shaped cyclo-hexyl ring. In the crystal, the cations and anions are linked by N-H?O and N-H?N hydrogen bonds, forming a layer network parallel to the ac plane. Weak ?-? inter-actions between adjacent pyridine rings with a centroid-centroid distance of 3.589?(2)?Å are also present.

In the dication of the title salt, C(6)H(16)N(2) (2+)·2C(6)H(4)NO(2) (-), the two ammonium groups are in the equatorial positions of the chair-shaped cyclo-hexyl ring. In the crystal, the cations and anions are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming a layer network parallel to the ac plane. Weak π-π inter-actions between adjacent pyridine rings with a centroid-centroid distance of 3.589 (2) Å are also present. ...[more]
