Summary:The crystal structure of bis(o-ethoxyphenyl)butadiyne has been determined by the statistical method of X-ray analysis. The space group is P21⁄a with two molecules in the unit cell of dimensions a=14.64, b=11.27, c=5.19 Å, and β=105.6°. The crystal structure is built up from columns of the molecules packed along the c-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.
