چکیده
In the title solvated molecular salt, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·CH(4)O, the pyridine N atom of 2-amino-4-methyl-pyridine is protonated and one carboxyl group of pyridine-2,6-dicarb-oxy-lic acid is deprotonated. The dihedral angles between the -CO(2) and -COH groups and the pyridine ring are 0.65 (13) and 7.4°. The crystal packing is stabilized by inter-molecular N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds.

In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·1.5H(2)O, extensive O-H⋯O, O-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, as well as ion pairing, π-π stacking inter-actions [centroid-centroid distances = 3.4690 (8) and 3.6932 (8) Å between aromatic rings] occur in the crystal. There are hydrogen-bonding inter-actions between water mol-ecules, which result in cyclic tetra-meric water clusters....

In the crystal structure of the title solvated salt, C(16)H(19)N(2) (+)·C(8)H(5)O(7)S(-)·CH(3)OH, the anions and the methanol solvent mol-ecules are linked by O-H⋯O hydrogen bonds. The cations and anions are packed as alternate layers parallel to (11[Formula: see text]). The crystal structure is further stabilized by a π-π inter-action between the pyridinium and benzene rings of the cations, wi...

The anion of the title salt, C(6)H(9)N(2) (+)·C(6)H(4)NO(3) (-), undergoes an enol-to-keto tautomerism during the crystallization. In the crystal structure, the cation and anion are held together by a relatively short N-H⋯O hydrogen bond, and the two anions are further connected to each other by a pair of N-H⋯O hydrogen bonds with an R(2) (2)(8) ring motif, thus forming a centrosymmetric 2 + 2 ...

The title compound, C(26)H(40)N(5)O(13)P·CH(3)OH·H(2)O, crystallizes with one water and one methanol mol-ecule providing important crystal-binding inter-actions. The compound has the unusual feature of having two but-oxy-carbonyl groups bound to one N atom. The conventional attractive hydrogen bonds involving hy-droxy, amine and water donors include bifurcations at both donors and acceptors wit...

In the 3-hy-droxy-picolinate anion of the title salt, C6H9N2 (+)·C6H4NO3 (-), an intra-molecular O-H⋯O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar, with a dihedral angle of 9.55 (9)° between the pyridine ring and the carboxyl-ate group. In the crystal, the cations and anions are linked via N-H⋯O hydrogen bonds, forming a centrosymmetric 2 + 2 ag...
