4-(Naphthalene-2-carboxamido)pyridin-1-ium thiocyanate–N-(pyridin-4-yl)naphthalene-2-carboxamide (1/1)
The asymmetric unit of the title compound, C(16)H(13)N(2)O(+)·NCS(-)·C(16)H(12)N(2)O, contains two N-(pyridin-4-yl)naphthalene-2-carboxamide mol-ecules, both are partially protonated in the pyridine moiety, i.e. the H atom attached to the pyridine N atom is partially occupied with an occupancy factor of 0.61 (3) and 0.39 (3), respectively. In the crystal, protonated and neutral N-(pyridin-4-yl)...

The asymmetric unit of the title salt, C12H14N2 (2+)·2C7H3N2O6 (-), comprises half a 4-[2-(pyridin-1-ium-4-yl)eth-yl]pyridin-1-ium dication, being disposed about a centre of inversion, and a 2,6-di-nitro-benzoate anion, in a general position. In the anion, the carboxyl-ate group is inclined to the benzene ring [dihedral angle = 85.45 (9)°], whereas near-coplanar and twisted arrangements are fou...

In the title compound, C(18)H(17)BrN(2)O(2), which is a potential -human immunodeficiency virus type 1 (HIV-1) non-nucleoside reverse transcriptase inhibitor, the pyrrolidine ring exhibits an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds [N⋯O = 2.861 (3) Å] link the mol-ecules into centrosymmetric dimers.

The title 1:1 co-crystal, C(7)H(7)NO(2)·C(10)H(8)N(2)S(2), features a highly twisted 4-(pyridin-4-yldisulfan-yl)pyridine mol-ecule [dihedral angle between the pyridine rings = 89.06 (10)°]. A small twist is evident in the 2-amino-benzoic acid mol-ecule, with the C-C-C-O torsion angle being -7.7 (3)°. An N-H⋯O hydrogen bond occurs in the 2-amino-benzoic acid mol-ecule. In the crystal, mol-ecules...

In the crystal structure of the title compound, C(4)H(6)N(3) (+)·C(7)H(7)O(3)S(-), inter-molecular N-H⋯O hydrogen bonds link the cations and anions into chains along [100]. Additional stabilization is provided by weak C-H⋯O hydrogen bonds. An inter-molecular π-π stacking inter-action with a centroid-centroid distance of 3.6957 (7) Å is also observed. The H atoms of the methyl group were refined...
