• The crystal structure of bis(<I>o</I>-ethoxyphenyl)butadiyne has been determined by the statistical method of X-ray analysis. The space group is <I>P</I>2<SUB>1</SUB>⁄<I>a</I> with two molecules in the unit cell of dimensions <I>a</I>=14.64, <I>b</I>=11.27, <I>c</I>=5.19 Å, and β=105.6°. The crystal structure is built up from columns of the molecules packed along the <I>c</I>-axis. The molecule has a center of symmetry and is almost planar. The diacetylene group is slightly twisted and the three conjugated bond distances of the diacetylene group are 1.434, 1.201, and 1.371 Å.
