Abstract
Abstract The ionic adduct of 2,6-dichloro-4-nitrophenol with 4-formylpyridine (which transforms into 4-dihydroxymethylpyridine), crystallizes in the space group P 2 1 c with a = 12.264(2), b = 6.730(1), c = 16.731(3) A , β = 99.46(3)° and Z = 4. Relatively long N+H⋯O− hydrogen bonds ( R N ⋯ = 2.683(3) A are formed with strongly asymmetric location of the H-atom. This is well reflected both in IR and UV-VIS spectra. One of the gem diol OH group is attached to the phenolate oxygen atom and the second is engaged in the formation of infinite polyanionic chains via OH⋯O hydrogen bonds between OH groups.
