2-(Aminocarbonyl)hydrazin-1-ium 6-carboxypicolinate
In the crystal structure of the title proton-transfer compound, CH(6)N(3)O(+)·C(7)H(4)NO(4) (-), O-H⋯O and N-H⋯O hydrogen bonds are formed respectively between the cations and the anions, each component affording a supra-molecular chain along the c axis. The cation and anion chains are further linked by N-H⋯O and N-H⋯N hydrogen bonds. A π-π inter-action is also observed between the pyridine rin...

In the cation of the title salt, C(11)H(12)IN(4) (+)·Cl(-), the two aromatic rings are oriented to each other at 9.3 (2)°. In the crystal, the two independent Cl(-) anions lie on twofold rotation axes. N-H⋯Cl hydrogen bonds between the cations and anions generate a supra-molecular layer parallel to (010).

In the title salt, C(6)H(10)N(3)O(+)·C(6)H(2)N(3)O(7) (-), the dihedral angle between the mean planes of the benzene and pyridine rings is 3.1 (1)°. In the cation, the meth-oxy group is almost coplanar with the pyridine ring [C-O-C-N = -0.6 (2)°]. The p-nitro [C-C-N-O = -1.17 (19)°] and one o-nitro [C-C-N-O = 1.83 (19)°] group in the anion are essentially coplanar with the benzene ring. The oth...
متن کاملCrystal structure of 6-ethoxypyridin-1-ium-2-olate
In the title compound, C7H9NO2, all non-H atoms are essentially coplanar [r.m.s. deviation = 0.032 Å]. The largest deviation from the plane of the pyridine ring is 0.105 (6) Å for the terminal C atom of the eth-oxy group. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers. These dimers are further linked by C-H⋯π inter-actions and weak π-π inter-act...
متن کامل2-Carboxy-6-(quinolin-1-ium-8-yloxy)benzoate
In the zwitterionic title compound, C(17)H(11)NO(5), the dihedral angle between the two aromatic rings is 76.90 (7)°. The dihedral angles between the carboxyl groups and the benzene ring are 64.02 (9) and 21.67 (9)°, the larger angle being associated with an intra-molecular N-H⋯O(carbox-yl) hydrogen bond, resulting from proton transfer from the carb-oxy-lic acid group to the quinoline N atom an...
