%X Four adducts of triphenylphosphine oxide with aromatic carboxylic acids have been synthesized and tested for second-order non-linear optical properties. These were with N-methylpyrrole-2-carboxylic acid (1), indole-2-carboxylic acid (2), 3-dimethylaminobenzoic acid (3), and thiophen-2-carboxylic acid (4). Compound (1) produced clear, colourless crystals (space group P 212121 with a 9&#183;892(1), b 14&#183;033(1), c 15&#183;305(1) &#197;, Z 4) which allowed the structure to be determined by X-ray diffraction.
