摘要：

The title compound nicotinic acid3,5-dinitrobenzoic acid (NDNT) has been obtained by the reaction of nicotinic acid with 3,5-dinitrobenzoic acid in deionic water at room temperature. The crystal is of monoclinic, space group P21/n with a = 14.053(6), b = 5.046(2), c = 20.105(8) ? ?= 103.573(8)? C13H9N3O8, Mr = 335.23, Z = 4, V = 1385.8(10) 3, Dc = 1.607 g/cm3, (MoK? = 0.137 mm-1, F(000) = 688, R = 0.0435 and wR = 0.0993 for 1239 observed reflections (I > 2(I)). In the crystals, the asymmetric unit contains one nicotinic acid (C6H5NO2) and one 3,5- dinitrobenzoic acid (C7H4N2O6) molecules which are linked by some hydrogen bonds to form a twenty-membered hydrogen-bonded ring and an extended linear structure.
