(E)-4-Hy-droxy-N'-(3,4,5-trimeth-oxy-benzyl-idene)benzohydrazide.

ABSTRACT: The title benzohydrazide derivative, C(17)H(18)N(2)O(5), exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 19.41?(5)°. The two meth-oxy groups at the meta positions of the trimeth-oxy-benzene group are almost coplanar with the ring [C-O-C-C = 1.62?(16) and 178.33?(10)°], whereas the third meth-oxy group, at the para position, is (+)-synclinal with the ring. In the crystal, mol-ecules are linked by N-H?O and bifurcated O-H?(N,O) hydrogen bonds, as well as weak C-H?O inter-actions, into sheets lying parallel to the ac plane. A C-H?? inter-action also occurs.

Project description:In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol-ecules. Both mol-ecules are twisted; the dihedral angle between the two benzene rings is 7.2?(5)° in one mol-ecule, whereas it is 85.9?(4)° in the other. Of the three meth-oxy groups in the 3,4,5-trimeth-oxy-phenyl unit, two meth-oxy groups at meta positions are approximately coplanar with the benzene plane [C-O-C-C torsion angles of -2.3?(13)-4.8?(11)°], but the other meth-oxy, at the para position, is out of the plane [C-O-C-C of 72.8?(9)° in one mol-ecule and -77.5?(9)° in the other]. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds and weak C-H?O inter-actions into tapes along the b axis. C-H?? inter-actions are also present.

Project description:The title compound, C(17)H(18)N(2)O(4), crystallizes with two independent mol-ecules in the asymmetric unit.

N'-(5-Chloro-2-hy-droxy-benzyl-idene)-4-meth-oxy-benzohydrazide.

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.

N'-(5-Chloro-2-hy-droxy-benzyl-idene)-2-meth-oxy-benzohydrazide.

Project description:The title Schiff base compound, C(15)H(13)ClN(2)O(3), was prepared by the reaction of equimolar quanti-ties of 5-chloro-2-hy-droxy-benzaldehyde with 2-meth-oxy-benzohydrazide in a methanol solution. The dihedral angle between the two benzene rings is 20.6?(3)°. An intra-molecular O-H?N hydrogen bond may influence the mol-ecular conformation. In the crystal structure, mol-ecules form chains along the b direction via inter-molecular N-H?O hydrogen bonds which are bifurcated involving an intra-molecular N-H?O hydrogen bond.
