Experimental details

The aromatic, methyl, methylene and hydroxyl hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93 Å, 0.96 Å, 0.97 Å and 0.82 Å and Uiso(H) = 1.2Ueq(C), 1.5Ueq(C), 1.2Ueq(C) and 1.2Ueq(C). The highest density peak lies within 0.49 Å from H6 and the deepest hole 0.60 Å from N1.

Discussion

The colorless organic acid, salicylic acid is widely used in organic synthesis, it functions as a plant hormone, it is an important active metabolite of aspirin, a key ingredient in many skin-care products and is used as an anti-inflammatory drug. 3,5-Dinitrosalicylic acid (2-hydroxy-3,5-dinitrobenzoic acid) is used to detect reducing substances in urine, for quantifying carbohydrate levels in blood and in assays of α-amylase. There are several crystal structure reports on 3,5-dinitrosalicylate with a variety of anions like 2-methoxyanilinium [1], 4-aminobenzenesulfonamide [2], 4-cyanopyridinium [3], ammonium [4], diethylammonium [5], 1-phenylethylaminium [6] and 3-(1H-imidazol-1-yl)propan-1-aminium [7] and some cases where 3,5-dinitrosalicylate is coordinated to copper(II) in a bidentate fashion [8, 9] but no structure reports the tetraethylammonium salt. Tetraethylammonium 3,5-dinitrosalicylate crystallized in the monoclinic P21/n spacegroup with one tetraethylammonium cation and one 3,5-dinitrosalicylate anion in the asymmetric unit (Figure 1). Four hydrogen bonding interactions are observed in the structure of the title compound, two intramolecular hydrogen interactions (O—H…O and C—H…O) and two intermolecular hydrogen interactions (C—H…O). Some π−π stacking is observed between the anions with centroid to centroid distances of 3.619 Å and 3.537 Å (Figure 2). The tetraethylammonium cations and 3,5-dinitrosalicylate anions pack in respective column-like structures when viewed along the b axis with the anions in an 180° alternating fashion. The carboxylic acid and the one nitro group (N2, O6, O7) are almost co-planar with the benzene ring with dihedral angles of 5.14(7)° and 3.25(8)° respectively. The second nitro group (N1, O4, O5) twists significantly from the plane through the benzene ring with a dihedral angle of 22.85(9)°.
