N2  - Five adducts consisting of carboxylic acid-substituted indoles with nitro-substituted benzoic acids have been synthesized and tested for second-order non-linear optical properties. These were indole-2-carboxylic acid with 2,4-dinitrobenzoic acid (1), 3,5-dinitrobenzoic acid (2), and 2,4,6-trinitrobenzoic acid (3), and indole-3-acetic acid with 3,5-dinitrobenzoic acid (4), and 2,4,6-trinitrobenzoic acid (5). Compound (2) produced clear, yellow crystals (space group P -1 with a 6&#183;8400(7), b 15&#183;150(2), c 16&#183;097(2) &#197;, &#945; 84&#183;911(9), &#946; 87&#183;088(10), &#947; 77&#183;865(9)&#176;, Z 4) which allowed the structure to be determined by X-ray diffraction. Of the five adducts, compounds (3) and (5) gave second harmonic intensities of 0&#183;15 and 0&#183;16 times respectively that of a urea standard.
