3-Chloro-N'-(4-diethyl-amino-2-hy-droxy-benzyl-idene)benzohydrazide.

ABSTRACT: The asymmetric unit of the title Schiff base compound, C(18)H(20)ClN(3)O(2), contains two independent mol-ecules. An O-H?N hydrogen bond contributes to the planarity of each mol-ecule: the dihedral angles between the two benzene rings are 12.8?(3) and 27.2?(3)° in the two mol-ecules. In the crystal, mol-ecules are linked through inter-molecular N-H?O hydrogen bonds, forming chains along the a axis.

The asymmetric unit of the title Schiff base compound, C(18)H(20)ClN(3)O(2), contains two independent mol-ecules. An O-H⋯N hydrogen bond contributes to the planarity of each mol-ecule: the dihedral angles between the two benzene rings are 12.8 (3) and 27.2 (3)° in the two mol-ecules. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains along the a axis. ...[more]

(E)-4-Amino-N'-(5-chloro-2-hy-droxy-benzyl-idene)benzohydrazide.

Project description:In the title hydrazide Schiff base compound, C(14)H(12)ClN(3)O(2), the conformation around the C=N double bond is E. The dihedral angle between the benzene rings is 41.57 (14) Å. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O (bifurcated acceptor) and N-H⋯N hydrogen bonds, forming chains along the a axis. The inter-esting feature of the crystal structure is the short inter-molecular C⋯O [3.216 (3), 3.170 (3), and 2.992 (3) Å] contacts, one of which is significantly shorter than the sum of the van der Waals radii of these atoms [3.22 Å].

Project description:The asymmetric unit of the title compound, C(15)H(13)ClN(2)O(3), contains two independent hydrazone mol-ecules. Each mol-ecule adopts an E configuration with respect to the methyl-idene unit and forms an intra-molecular O-H?N hydrogen bond.
