Crystal structures of (E)-1-{3-[(5-fluoro-2-hydroxybenzylidene)amino]phenyl}ethanone and of a fourth polymorph of (E)-1-{3-[(2-hydroxy-3-methoxybenzylidene)amino]phenyl}ethanone
In the mol-ecules of both (E)-1-{3-[(5-fluoro-2-hy-droxy-benzyl-idene)amino]-phen-yl}ethanone, C15H12FNO2, (I), and (E)-1-{3-[(2-hy-droxy-3-meth-oxy-benzyl-idene)amino]-phen-yl}ethanone, C16H15NO3, (II), which crystallizes with Z' = 2 in space group Pca21, there are intra-molecular O-H⋯N hydrogen bonds, and the non-H atoms in each mol-ecule are essentially coplanar. In the crystal of (I), mol-e...
متن کاملCrystal structure of (E)-1-(3-chlorophenyl)-3-(furan-2-yl)prop-2-en-1-one
The title compound, C13H9ClO2, exhibits a non-planar geometry; the furan ring being inclined to the benzene ring by 50.52 (16)°. In the crystal, mol-ecules stack along the a axis; however, there are no significant inter-molecular inter-actions present.
متن کاملCrystal structure of (E)-N′-(3-fluoro-2-hydroxybenzylidene)isonicotinohydrazide
In the title compound, C13H10FN3O2, the mol-ecule has an E conformation with respect to the C=N bond of the hydrazone bridge. The dihedral angle between the isonicotinoyl and fluoro-phenol moieties is 4.03 (4)°, and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯N and C-H⋯N hydrogen bonds, forming chains propagating along the a-...

The asymmetric unit of the title 1:2 adduct, C(12)H(10)N(4)·2C(8)H(8)O(2), comprises a single mol-ecule of 2-phenyl-acetic acid and half a mol-ecule of 3-pyridine-aldazine; the latter is completed by crystallographic inversion symmetry. In the crystal, mol-ecules are connected into a three-component aggregate via O-H⋯N hydrogen bonds. As the carboxyl group lies above the plane through the benze...

In the title compound, C16H13FO3S, the dihedral angle between the mean planes of the benzo-furan ring system and the 3-methyl-phenyl ring is 80.96 (4)°. In the crystal, mol-ecules are linked via pairs of π-π inter-actions between furan and benzene rings, with centroid-centroid distances of 3.758 (1) and 3.771 (1) Å. A similar inter-action is found between furan rings, with a centroid-centroid d...
