N2  - The 1 : 2 molecular adduct between phenoxyacetic acid and 3,5-dinitrobenzoic acid, with formula [(C6H5OCH2COOH)2{3,5-(NO2)2C6H3COOH}4(H2O)2], has been prepared and its structure determined by X-ray diffraction. Crystals are triclinic, space group P&#299; with two complex units in a cell with dimensions a 7.202(2), b 18.519(5), c 20.924(6)&#506;, &#945; 66.33(3),&#946; 86.04(2),&#947; 89.32(2)&#176;. The molecular repeating unit comprises two phenoxyacetic acid molecules [forming hydrogen-bonded cyclic dimers (O&#823;O, 2.71, 2.74 &#506;)], four 3,5- dinitrobenzoic acid molecules [giving two unusual one-bond hydrogen bonds (O&#8230;O, 2.59, 2.64&#506;)] and two water molecules. The waters are intimately involved in a hydrogen-bonding network with carboxylic acid oxygens.
