N2  - A number of molecular adducts of nitro-substituted aromatic acids with Lewis bases have been prepared and characterized by infrared spectroscopy and in three cases by X-ray diffraction methods. These three compounds are the adducts of: 3,5-dinitrobenzoic acid (dnba) with N-methylaniline (nma), &#91;(dnba)-(nma)+&#93; (1); (4-nitrophenyl)acetic acid (4-npa) with cyclohexane-1,4-diamine (dach), &#91;(4-npa)22-(dach)2+&#93; (4); 5-nitrosalicylic acid (5-nsa) with 2-imidazolidone (idaz), &#91;(5-nsa)2(idaz)&#93; (5). Other compounds are the adducts of 3,5-dinitrobenzoic acid with 2,6-dimethylpyridine (dmp), &#91;(dnba)(dnba)-(dmp)+&#93; (2), and with 1-methylpyrrole-2-carboxylic acid (cmp), &#91;(dnba)-(cmp)+&#93; (3). Compounds (1) and (3) have 1 : 1 stoichiometry, while (2), (4) and (5) are 2 : 1 adducts. Proton transfer occurs in most examples &#91;complex (5) is the exception&#93;.
