title: 2-[4-(2-Formyl-phen-oxy)-but-oxy]-benzaldehyde.
abstract: In the crystal structure of the title compound, C(18)H(18)O(4), the full mol-ecule is generated by the application of an inversion centre. The mol-ecule is essentially planar, with an r.m.s. deviation of 0.017 (1) Å for all non-H atoms. The mol-ecules are linked through inter-molecular C-H⋯O inter-actions to form a mol-ecular sheet parallel to the ([Formula: see text]02) plane.
