1,10-Bis[2-(prop-1-en-yl)phen-oxy]deca-ne.

The complete molecule of the title compound, C(28)H(38)O(2), is generated by a crystallographic centre of symmetry. The molecular conformation displays an intra-molecular C-H⋯π inter-action.

1,4-Bis[2-(prop-1-en-yl)phen-oxy]butane.

The mol-ecule of the title compound, C(22)H(26)O(2), exhibits C(i) mol-ecular symmetry with a crystallographic inversion centre at the mid-point of the central C-C bond. A kink in the mol-ecule is defined by the torsion angle of 66.7 (2)° about this central bond of the alkyl bridge.
