چکیده
The mol-ecule of the title compound, C(40)H(46)S(2), reveals C(i) symmetry. An inversion centre is located at the mid-point of the C-C bond of the biphenyl unit; the asymmetric unit comprises one-half of the mol-ecule. The conjugated backbone is nearly planar, with a mean deviation of 0.041 Å.

4,4′-Bis[(E)-(2,3-diiodoprop-2-en-1-yl)oxy]biphenyl
Iodine adds across both triple bonds of 4,4'-bis-(prop-2-yn--yl-oxy)biphenyl, yielding the 4,4'-bis-(2,3-diiodo-all-yloxy)biphenyl title compound, C(18)H(14)I(4)O(2); the 2,3-diiodo-ally-oxy substituents have the I atoms in an E configuration. In the biphenyl portion of the mol-ecule, the aromatic rings are inclined by 37.8 (2)°.

متن کامل4,4′-Bis(2-methoxylstyryl)biphenyl
The title compound, C(30)H(26)O(2), was prepared by the reaction of a Wittig reagent and 2-methoxy-benzaldehyde. The mol-ecule lies about an inversion centre located at the midpoint of the C-C bond between the inner benzene rings. The crystal structure is stabilized by C-H⋯π inter-actions.
متن کامل4,4′-Bis(prop-2-ynyloxy)biphenyl
The title compound, C(18)H(14)O(2), crystallizes with one half-mol-ecule in the asymmetric unit. The mol-ecule lies on an inversion center, located at the mid-point of the central C-C bond. As a result, the benzene rings are coplanar. No classical hydrogen bonds or stacking inter-actions are observed in the crystal structure.
