Microwave spectra of pyridine and monodeuterated pyridines. Revised molecular structure of pyridine
Journal of Molecular Structure, 1977Abstract The microwave spectra of pyridine and its 2-D, 3-D and 4-D substituted species were reinvestigated. Nuclear quadrupole coupling and centrifugal distortion effects were considered also for the deuterated species resulting in improved values for the rotational constants of these species.

Interactions of pyridine perchlorate with pyridine in acetonitrile
Journal of Molecular Liquids, 1983Abstract The IR and 1 H measurements of pyridine perchlorate in acetonitrile as a function of concentration of added pyridine were determined and K app = (K 1 + K 2 K d )/(1 + K d ) = 3.1 ± 0.1 obtained. Equilibrium constant of B + H⋯ A − ⇌B + H + A − was determined by conductometric technique (K d = 1.75×10 −2 moldm −3 ). Using published value

Role of Pyridine in Wyodak−Pyridine Adducts
Energy & Fuels, 2005When pyridine (PYR) is added to powdered Wyodak subbituminous coal (WYO), the sample is converted to a paste, and the molecular-level adduct which is formed is stable for months. After the excess pyridine has evaporated from the WYO−PYR sample, the stoichiometry of the adduct is ca.

Synthesis of Pluriaminated Pyridines
HETEROCYCLES, 1998The key reagent 3,5-dichloro-4-pyridinecarbonitrile (1) was used to synthesize 4-aminomethylpyridine derivatives 3,5-disubstituted with various amino groups, very active as inhibitors of diamine oxidase. The study of the reaction allowed to discover conditions for the gradual substitution in good yields of the two chlorine atoms to give symmetrically ...

Crystal structures of pyridine and pyridine trihydrate
The Journal of Chemical Physics, 1981The crystal structure of pyridine is orthorhombic with space group Pna21, a = 1752.4(3), b = 896.9(2), and c = 1135.2(2) pm at 153 K and Z = 16. A low melting crystalline hydrate of pyridine was found by DTA to be a trihydrate. It is orthorhombic, too, with space group Pbca, a = 1244.4(3), b = 1783.2(6), and c = 679.1(2) pm at 223 K and Z = 8.

Microbial Degradation of Pyridine and Pyridine Derivatives
2019Pyridine derivatives belong to an important class of aromatic compounds that occur largely as a result of human activities, although they are not necessarily xenobiotic compounds. Pyridines can also be derivatized to form a wide variety of xenobiotic compounds ranging from drugs to pesticides. Analogs to phenolic compounds, pyridines exhibit properties
