(E)-2-Chloro-N'-(4-hy-droxy-benzyl-idene)-benzohydrazide.

ABSTRACT: The title hydrazone mol-ecule, C(14)H(11)ClN(2)O(2), has a trans conformation with respect to the methyl-idene unit. The dihedral angle between the two benzene rings is 37.6?(3)°. In the crystal, the presence of O-H?O, O-H?N and N-H?O hydrogen bonds leads to the formation of a three-dimensional network. The title compound crystallized in the chiral ortho-rhom-bic space group P2(1)2(1)2(1) and was refined as an inversion twin [Flack parameter = -0.20?(18)].

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. The principal difference between the two unique mol-ecules is the relative orientation of the two benzene rings, the dihedral angles between them being 4.0?(3) and 65.9?(3)°, respectively. In the crystal, mol-ecules are linked through N-H?O hydrogen bonds, forming chains running along the c axis.

(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.
