(E)-3-(2,3-Dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one
The mol-ecular conformation of the title compound, C(18)H(18)O(5), is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The C=C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1)°.
متن کامل(2E)-3-(3-Benzyloxyphenyl)-1-(2-hydroxy-5-methylphenyl)prop-2-en-1-one
In the mol-ecule of the title compound, C(23)H(20)O(3), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The central benzene ring makes dihedral angles of 80.17 (8) and 16.99 (7)°, respectively, with the benz-yloxy and hy-droxy-methyl phenyl rings. In the crystal, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds to form dimers. The dimers are connected by C-H⋯O hydro...

In the title compound, C24H18N2OS, the pyridine and the two phenyl rings are oriented at dihedral angles of 10.1 (5), 71.7 (6) and 68.7 (5)°, respectively, to the central thio-phene ring. In the crystal, pairs of weak C-H⋯O hydrogen bonds link inversion-related mol-ecules, forming dimers. The dimers are linked by further weak C-H⋯O hydrogen bonds, forming chains running along the a-axis direction.

In the title compound, C(17)H(16)BrNO(2), the two benzene rings make a dihedral angle of 7.4 (3)°; the hy-droxy group links to the carbonyl group via an intra-molecular O-H⋯O hydrogen bond. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into a supra-molecular chain running along the c axis.

In the title compound, C(16)H(15)BrO(4)S, the dihedral angle between the thio-phene and benzene rings is 13.08 (16)°. The C atoms of the meta meth-oxy groups of the substituted benzene ring lie close to the plane of the ring [displacements = 0.049 (5) and -0.022 (4) Å], whereas the para-C atom is significantly displaced [-1.052 (4) Å]. In the crystal, mol-ecules are linked by weak C-H⋯O hydroge...
