Pyridine is a basic heterocyclic organic compound with the chemical formula C5H5N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell. Pyridine is colorless, but older or impure samples can appear yellow, due to the formation of extended, unsaturated polymeric chains, which show significant electrical conductivity. The p… WebOct 19, 2024 · The formation process of a hybrid inorganic–organic 2D transition metal nitroprussides remains well documented for pyridine and its derivatives, 18–21 pyrazine, 22 and 4,4′-azopyridine, 23 and 1-methyl-2-pyrrolidone. 24 The hybrid solid is obtained using both a precipitation reaction, as mentioned above, or exfoliating the 3D phase under …
