“…The hydroxyl group is linked to the O atom, O(21), of the o-nitro group forming an intramolecular hydrogen bond. The O(1)...O(21) distance is 2.615 (5) A, which is longer than the corresponding hydrogen-bond distances found in 2,6-DNP (lwasaki, Sato & Aihara, 1976), 2-chloro-4,6-dinitrophenol (2-C1-4,6-DNP, Andersen & Andersen, 1975) and 2-bromo-4,6-dinitrophenol (2-Br-4,6-DNP, Neustadt & Cagle, 1975).…”

Crystals of 2,4-dinitrophenol, C6H4N205, are orthorhombic, space group P2,2~2, with cell dimensions: a = 6.102 (3), b : 23.202 (8), c = 5.178 (4) A and Z : 4. The structure was solved by an inspection of a Patterson map and R maps and refined by the full-matrix least-squares method to the final R value of 0-048 for 885 diffractometer-collected reflexions. The hydroxyl group is linked to one of the O atoms of the ortho-nitro

“…The o-quinonoid nature of the benzene ring is remarkable, as in 2-nitro-4-chlorophenol and 2-bromo-4,6-dinitrophenol (Neustadt & Cagle, 1975). The C-N bond lengths are rather short but agree well with the values C(2)-N(1) 1.457, C(4)-N(2) 1.460 A calculated from the O-N-O angle by the formula proposed by Kawai, Kashino & Haisa (1976).…”
