| description | In the title compounds, (2E,20E)-3,30-(1,4-phenylene)bis[1-(2-methoxyphenyl)-
prop-2-en-1-one], C26H22O4 (I), (2E,20E)-3,30-(1,4-phenylene)bis[1-(3-methoxyphenyl)
prop-2-en-1-one], C26H22O4 (II) and (2E,20E)-3,30-(1,4-phenylene)bis[1-
(3,4-dimethoxyphenyl)prop-2-en-1-one], C28H26O6 (III), the asymmetric unit
consists of a half-molecule, completed by crystallographic inversion symmetry.
The dihedral angles between the central and terminal benzene rings are
56.98 (8), 7.74 (7) and 7.73 (7) for (I), (II) and (III), respectively. In the crystal
of (I), molecules are linked by pairs of C—H interactions into chains
running parallel to [101]. The packing for (II) and (III), features inversion
dimers linked by pairs of C—HO hydrogen bonds, forming R2
2(16) and R2
2(14)
ring motifs, respectively, as parts of [201] and [101] chains, respectively. |
