2-Methoxy-benzohydrazide.

Project description:The title compound, C(8)H(10)N(2)O(2), crystallizes as two independent mol-ecules linked by N-H?N and N-H?O hydrogen bonds into a linear chain running along the a axis of the monoclinic unit cell. The intra- and inter-molecular hydrogen bonds are described as a two-ring R(2) (2)(10) motif. The six-membered R(1) (1)(6) rings formed by the intra-molecular inter-actions are almost planar (r.m.s. deviations 0.06 and 0.08?Å). In one mol-ecule, the aromatic and hydrogen-bonded rings are oriented at 4.8?(2)°, whereas in the other mol-ecule these rings are oriented at 6.1?(4)°.

N'-(2-Hydr-oxy-4-methoxy-benzyl-idene)-4-methoxy-benzohydrazide.

Project description:In the title compound, C(16)H(16)N(2)O(4), the dihedral angle between the two benzene rings is 8.7?(2)°. The mol-ecule adopts an E configuration about the C=N bond, with an intra-molecular O-H?N hydrogen bond involving the hydr-oxy substituent and the hydrazide N atom. In the crystal structure, adjacent mol-ecules are linked through inter-molecular N-H?O hydrogen bonds, forming chains propagating in the b-axis direction.

(E)-N'-(5-Bromo-2-methoxy-benzyl-idene)-3-methoxy-benzohydrazide.

Project description:In the title compound, C(16)H(15)BrN(2)O(3), there are two independent mol-ecules (A and B) in the asymmetric unit. The major difference between the two mol-ecules is the dihedral angle formed by the aromatic rings [72.6 (2) and 18.8 (2)° for A and B, respectively]. The benzohydrazide groups are not planar and the mol-ecules exist in trans configurations with respect to the methyl-idene units. The mol-ecular packing is stabilized by two inter-molecular N-H⋯O hydrogen bonds, forming chains parallel to the c axis. Only the A mol-ecules of the asymmetric unit are held together by π-π inter-actions [centroid-centroid distance = 3.714 (3) Å].
