2-[(E)-(2,4-Dimethyl-phen-yl)imino-meth-yl]phenol.

Project description:The asymmetric unit of the title compound, C(15)H(15)NO, contains two independent mol-ecules, both of which exist in trans configurations with respect to the C=N bonds [1.278?(2) and 1.279?(2)?Å]. In each mol-ecule, intra-molecular O-H?N hydrogen bonds generate S(6) ring motifs. In one mol-ecule, the benzene rings form a dihedral angle of 13.38?(9)°, while in the other mol-ecule the dihedral angle is 30.60?(10)°. In the crystal, the two independent mol-ecules are linked via weak inter-molecular C-H?O hydrogen bonds.

2-[(2,4-Dimethyl-phen-yl)imino-meth-yl]-3,5-dimethoxy-phenol.

Project description:X-ray analysis reveals that the title Schiff base compound, C(17)H(19)NO(3), possesses both OH and NH tautomeric character in its mol-ecular structure. The occupancies of the enol and keto tautomers are 0.62?(3) and 0.38?(3), respectively. The presence of the minor keto form could not be confirmed from the IR spectrum. The mol-ecule is approximately planar, the dihedral angle between the planes of the two aromatic rings being 6.97?(8)°. The mol-ecular structure of the major component is stabilized by an intra-molecular O-H?N hydrogen bond, which generates an S(6) ring motif (N-H?O hydrogen bond in the minor component).

2-[(2,4-Dimethyl-phen-yl)imino-meth-yl]-6-methyl-phenol.

Project description:The title compound, C(16)H(17)NO, is a Schiff base which adopts the phenol-imine tautomeric form in the solid state. The mol-ecule is almost planar, with a dihedral angle of 4.61 (4)° between the aromatic rings. The molecular structure is stabilized by an intramolecular O-H⋯N hydrogen bond which generates a six membered ring.

5-Diethyl-amino-2-[(E)-(2,4-dimeth-oxy-phen-yl)imino-meth-yl]phenol.

Project description:The title Schiff base, C(19)H(24)N(2)O(3), exists in the crystal structure in the phenol-imine tautomeric form with an intra-molecular O-H?N hydrogen bond. The planes of the aromatic rings form a dihedral angle of 36.8?(8)°. The crystal packing is characterized by C-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.478?(4)Å].

2,4-Di-bromo-6-{[(5-chloro-2-methyl-phen-yl)imino]-meth-yl}phenol.

Project description:In the mol-ecular structure of the title Schiff base, C14H10Br2ClNO, the chloro-phenyl ring and di-bromo-phenol ring are almost coplanar; the dihedral angle between the planes of the two rings is 10.50 (18)°. There is an intra-molecular O-H⋯N hydrogen bond, with an O⋯N distance of 2.576 (4)Å. The crystal structure is stabilized by π-π stacking of neighbouring aromatic rings along the b-axis direction [centroid-centroid distance = 3.6896 (5) Å].

2,4-Diiodo-6-[(propyl-imino)-meth-yl]phenol.

Project description:The title compound, C(10)H(11)I(2)NO, was prepared by the reaction of 3,5-diiodo-salicyl-aldehyde with propyl-amine in ethanol. The mol-ecule adopts an E conformation with respect to the C=N bond and the aromatic ring. The aromatic ring and the imino unit are close to being coplanar, with a dihedral angle of 2.6?(3)° between their planes. This planarity is assisted by the formation of an intra-molecular O-H?O hydrogen bond.

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

Project description:In the title Schiff base compound, C(15)H(15)NO(2), prepared from 4-meth-oxy-benzyl-amine and salicyl-aldehyde, an intra-molecular O-H?N hydrogen bonds influences the mol-ecular conformation; the two aromatic rings form a dihedral angle of 73.5?(1)°. In the crystal, weak inter-molecular C-H?O inter-actions link the mol-ecules into chains propagating in [010].
