2-{(E)-[(3-Iodo-4-methyl-phen-yl)imino]-meth-yl}-4-(trifluoro-meth-oxy)phenol.

ABSTRACT: The title compound, C(15)H(11)F(3)INO(2), adopts the enol-imine tautomeric form. The mol-ecule displays an E conformation with respect to the imine C=N double bond. The dihedral angle between the two benzene rings is 12.4 (2)°. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring motif. The trifluoro-meth-oxy-phenyl group is disordered over two sites with an occupancy ratio of 0.621 (6):0.379 (6). The crystal structure features C-H⋯π inter-actions.

4-Meth-oxy-2-{(E)-[(thio-phen-2-yl)methyl-imino]-meth-yl}phenol.

Project description:The title Schiff base, C(13)H(13)NO(2)S, adopts the phenol-imine tautomeric form and reveals an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy group and the imino N atom, forming an S(6) ring. The mol-ecule is highly twisted with respect to the central imine group, which is reflected in the dihedral angle of 67.83 (10)° formed by the thienyl and phenol rings. The crystal packing is characterized by weak C-H⋯O and C-H⋯π inter-actions.

2-Eth-oxy-6-{(E)-[(4-methyl-phen-yl)imino]-meth-yl}phenol.

Project description:The asymmetric unit of the title compound, C(16)H(17)NO(2), contains two mol-ecules in which the dihedral angles between the 3-eth-oxy-2-hy-droxy-benzaldehyde and toluidine moieties are 16.87 (8) and 19.93 (6)°. S(6) rings are present in both mol-ecules due to intra-molecular O-H⋯N hydrogen bonds. In the crystal, one of the mol-ecules is dimerized with an inversion-generated partner, due to two C-H⋯O inter-actions. This generates an R(2) (2)(8) loop.

2-[(2,6-Diisopropyl-phen-yl)imino-meth-yl]-4-iodo-phenol.

Project description:The asymmetric unit of title compound, C(19)H(22)INO, contains two independent mol-ecules. Classical intra-molecular O-H?N hydrogen bonds stabilize the mol-ecular structures. The crystal structure is stabilized by weak inter-molecular C-H?? and ?-? [centroid-centroid = 3.8622?(18)?Å] inter-actions. In both mol-ecules, the aromatic rings are nearly perpendicular to each other [dihedral angles = 84.26?(17) and 86.69?(15)°].

2-[(E)-(Naphthalen-2-yl-imino)-meth-yl]-4-(trifluoro-meth-oxy)phenol.

Project description:In the title compound, C(18)H(12)F(3)NO(2), the planes of the benzene ring and the naphthalene system form a dihedral angle of 47.21 (3)°. The hy-droxy group is involved in an intra-molecular O-H⋯N hydrogen bond. In the crystal, weak C-H⋯O and C-H⋯F inter-actions link the mol-ecules related by translations along the c and a axes, respectively, into sheets.

3-Meth-oxy-2-[(E)-(4-meth-oxy-phen-yl)imino-meth-yl]phenol.

Project description:The title compound, C(15)H(15)NO(3), adopts the enol-imine tautomeric form. The two rings are twisted with respect to each other, making a dihedral angle of 44.08 (5)°. The 3-methoxy-2-[(E)-(4-methoxyphenyl)-iminomethyl]phenol unit is almost planar, the largest deviation from the mean plane being 0.047 (2) Å. Such a planar conformation might be related to the occurrence of an intra-molecular O-H⋯N hydrogen bond. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into sheets parallel to (010). These sheets are inter-connected by weak C-H⋯π inter-actions.

2-[(4-Meth-oxy-2-nitro-phen-yl)imino-meth-yl]phenol.

Project description:The crystal structure of the title compound, C(14)H(12)N(2)O(4), contains four crystallographically independent mol-ecules in the asymmetric unit.
