1,4-Bis[(3,5-dimethoxy-phen-yl)ethyn-yl]benzene.

ABSTRACT: The title compound, C(26)H(22)O(4), is a derivative of 1,4-bis-(phenyl-ethyn-yl)benzene substituted by four meth-oxy groups on the terminal benzene rings. The mol-ecule is almost planar with an r.m.s. deviation of 0.266?Å. The dihedral angles between the two terminal benzene rings and the central benzene ring are 7.96?(6) and 13.32?(7)°. In the crystal structure, mol-ecules aggregate via C-H?O inter-actions, forming mol-ecular tapes along the a axis, which aggregate to form a herring-bone structure.
