(2E,6E)-2,6-Bis(2-fluoro-5-meth-oxy-benzyl-idene)cyclo-hexan-1-one.

ABSTRACT: The title compound, C(22)H(20)F(2)O(3), a derivative of curcumin, crystallized with two independent mol-ecules in the asymmetric unit. The mean planes of the two 2-fluoro-5-meth-oxy-phenyl groups are aligned at 24.88?(11)° in one mol-ecule and 24.19?(15)° in the other. The dihedral angles between the mean plane of the penta-1,4-dien-3-one group and those of the two 2-fluoro-5-meth-oxy-phenyl rings are 51.16?(11) and 49.16?(10)° in the first mol-ecule, and 45.69?(15) and 54.00?(14)° in the second. The mol-ecules adopt E configurations about the central olefinic bonds.

The title compound, C(22)H(20)F(2)O(3), a derivative of curcumin, crystallized with two independent mol-ecules in the asymmetric unit. The mean planes of the two 2-fluoro-5-meth-oxy-phenyl groups are aligned at 24.88 (11)° in one mol-ecule and 24.19 (15)° in the other. The dihedral angles between the mean plane of the penta-1,4-dien-3-one group and those of the two 2-fluoro-5-meth-oxy-phenyl rings are 51.16 (11) and 49.16 (10)° in the first mol-ecule, and 45.69 (15) and 54.00 (14)° in the second ...[more]

Project description:The title compound, C(22)H(20)O, shows an approximately planar cyclo-hexenone ring [maximum deviation = 0.069?(4)?Å], with a disordered position of the C=C bond [ratio = 0.71?(2)/0.29?(2)].

Project description:In the title structure, C21H20O5·C2H5OH, the curcumine-type mol-ecule has a double E conformation for the two benzyl-idene double bonds [C=C = 1.342?(4) and 1.349?(4)?Å] and is nearly planar with respect to the non-H atoms (r.m.s. deviation from planarity = 0.069?Å). The two phenolic OH groups form bifurcated hydrogen bonds with intra-molecular branches to adjacent meth-oxy O atoms and inter-molecular branches to either a neighbouring mol-ecule or an ethanol solvent mol-ecule. The ethanol O atom donates a hydrogen bond to the keto O atom. These hydrogen bonds link the constituents into layers parallel to (101) in the crystal structure.

Project description:In the title compound, C(9)H(11)N(3)O(3), two mol-ecules are present in the asymmetric unit in which the 4-hy-droxy-3-meth-oxy-benzaldehyde and hydrazinecarboxamide units are almost planar [with r.m.s. deviations 0.0212 and 0.0066 Å, respectively, in one mol-ecule and 0.0346 and 0.0095 Å, respectively, in the other] and are oriented at dihedral angles of 9.7 (3) and 16.6 (3)°. In both mol-ecules, two S(5) ring motifs are present due to N-H⋯N and O-H⋯O hydrogen bonds. In the crystal, the mol-ecules are dimerized with each other due to pairs of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. O-H⋯O hydrogen bonds lead to the formation of a three-dimensional network.
