ABSTRACT
The title compound, C(19)H(23)N(3)O(2), was prepared by condensing 4-diethyl-amino-2-hy-droxy-benzaldehyde and 4-methyl-benzo-hydrazide in methanol. The asymmetric unit contains two independent mol-ecules in which the two benzene rings make dihedral angles of 30.3â (3) and 18.9â (3)°. Intra-molecular O-Hâ¯N hydrogen bonds are observed in both mol-ecules. The crystal structure is stabilized by N-Hâ¯O hydrogen bonds, which form chains along the a axis.
ABSTRACT
The title compound, C(15)H(14)N(2)O(3), was prepared by condensing 4-hy-droxy-benzaldehyde and 2-hy-droxy-3-methyl-benzo-hydra-zide in methanol. The two benzene rings make a dihedral angle of 19.03â (11)°. An intra-molecular O-Hâ¯O hydrogen bond is observed. The crystal structure is stabilized by inter-molecular O-Hâ¯O and N-Hâ¯O hydrogen bonds and C-Hâ¯O inter-actions, which lead to the formation of a three-dimensional network.
