چکیده
In the title compound, C(20)H(19)O(4), the benzene rings, linked via five methyl-ene C atoms, form a dihedral angle of 77.28 (6)°. In the crystal, mol-ecules are linked via pairs of weak C-H⋯O inter-actions [graph set R(2) (2)(6)] into dimers that are further connected by additional weak C-H⋯O interactions [graph sets R(2) (2)(14), R(2) (2)(26) and R(2) (2)(6)].

4-{2-[2-(4-Formylphenoxy)ethoxy]ethoxy}benzaldehyde
The title compound, C(18)H(18)O(5), was obtained by the reaction of 4-hy-droxy-benzaldehyde with bis-(2,2-dichloro-eth-yl) ether in dimethyl-formamide. In the crystal, the mol-ecule lies on a twofold rotation axis that passes through the central O atom of the aliphatic chain, thus leading to one half-mol-ecule being present per asymmetric unit. The carbonyl, aryl and O-CH(2)-CH(2) groups are al...

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.
