HYDROGEN BONDING OF PYRIDINE-CARBOXYLIC ACIDS IN SOLIDS

Chemistry Letters, 1973
Abstract The nature of the hydrogen bonds in pyridine-carboxylic acids is studied theoretically. There is an interesting relationship between O···N and N···H distances in the systems. The relation can be reasonably explained by the consideration of the charge transfer interactions.

Synthesis and structural characteristic of pyridine carboxylic acids adducts with squaric acid

CrysteEngComm, 2022
In this work, squaric acid (3,4-dihydroxycyclobut-3-ene-1,2-dione) was used as a coformer to pyridine carboxylic acids cocrystallization. Among three newly prepared complexes are an example of a salt–cocrystal continuum – pyridinium-2-carboxylate...

Complexes of Carboxylic Acids with Pyridines and Pyridine N-Oxides

HETEROCYCLES, 1994
A brief survey is given of dielectric, spectroscopic, thermodynamic, colligative and conductivity properties of non-aqueous solutions of carboxylic acid complexes with pyridines and pyridine N-oxides. Selected problems of solid state are also reviewed.
