(E)-2-[(2-Amino-4,5-dibromo-phen-yl)imino-meth-yl]-6-methoxy-phenol.

ABSTRACT: The title compound, C(14)H(12)Br(2)N(2)O(2), was prepared from the condensation of 4,5-dibromo-1,2-phenyl-enediamine and 2-hydr-oxy-3-methoxy-benzaldehyde in methanol. The N=C double bond shows a trans conformation and the dihedral angle between the aromatic ring planes is 5.9?(4)°. In the crystal structure, there are intra-molecular O-H?N and N-H?N and inter-molecular N-H?O hydrogen bonds, the latter resulting in inversion dimers.

(E)-2-[(4-Ethoxy-phen-yl)imino-meth-yl]-4-methoxy-phenol.

Project description:In the mol-ecule of the title compound, C(16)H(17)NO(3), the aromatic rings are oriented at a dihedral angle of 29.25?(8)°. An intra-molecular O-H?N hydrogen bond results in the formation of a nearly planar [maximum deviation 0.034?(13)?Å] six-membered ring, which is oriented at dihedral angles of 0.91?(1) and 28.91?(12)° with respect to the aromatic rings. The title mol-ecule is a phenol-imine tautomer, as evidenced by C-O, C-N and C-C bond lengths. In the crystal, mol-ecules are linked by inter-molecular C-H?O hydrogen bonds that generate C(8) chains.

2-{(E)-[4-(Di-phenyl-amino)-phen-yl]imino-meth-yl}phenol.

Project description:The asymmetric unit of the title Schiff base molecule, C25H20N2O, contains two independent mol-ecules. In each mol-ecule, the C=N bond is in an E conformation. The most significant difference between the two mol-ecules is seen for the dihedral angles between the meth-oxy-substituted benzene ring and the two phenyl rings, which are 85.5 (1) and 82.3 (1)° in the first mol-ecule, and 49.0 (1) and 40.4 (1)° in the second. This conformational difference is reflected in the central C=N-C C torsion angle, which is 28.7 (2)° in the first mol-ecule and -29.8 (3)° in the other. In each mol-ecule, there is an intra-molecular O-H⋯N hydrogen bond.

Project description:The title compound, C(14)H(11)Br(2)NO, was prepared by the condensation of benzyl-amine and 3,5-dibromo-2-hydroxy-benzaldehyde.
