(Received 21 November 2011; accepted 22 November 2011; online 25 November 2011)

The title compound, C16H16N2O2, is the product of the reaction of 4-meth­oxy­benzaldehyde and 4-methyl­benzo­hydrazide. The dihedral angle between the substituted benzene rings is 17.6 (3)° and the meth­oxy C atom is almost coplanar with its attached ring [deviation = 0.019 (4) Å]. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, forming C(4) chains propagating along the b-axis direction.

Comment top

Recently, the compounds derived from the condensation reaction of carbonyl-containing compounds with substituted benzohydrazides have received considerable attention. In this paper, the title new compound, derived from the reaction of 4-methoxybenzaldehyde with 4-methylbenzohydrazide, is reported.

The molecule of the compound, Fig. 1, displays a trans-configuration about the C9 ═N2 bond. The torsion angle of C8—N1—N2—C9 is 2.3 (3)°. The dihedral angle between the C2—C7 and C10—C15 benzene rings is 17.6 (3)°, indicating the molecule of the compound is twisted. Overall, the bond distances are within normal values (Allen et al., 1987), and are comparable with those reported in similar compounds (Horkaew et al., 2011; Fun et al., 2011; Su et al., 2011; Hashemian et al., 2011; Promdet et al., 2011). In the crystal, molecules are linked by N—H···O hydrogen bonds (Table 1) to form C(4) chains along the b axis (Fig. 2).

Experimental top

The title compound was synthesized by the reaction of 4-methoxybenzaldehyde (1 mmol, 0.14 g) with 4-methylbenzohydrazide (1 mmol, 0.15 g) in absolute methanol (30 ml) at ambient condition. Colorless prism-shaped single crystals were obtained by slow evaporation of the solution at room temperature after several days.

Refinement top

The amide H atom was located in a difference map and was refined isotropically, with N—H = 0.90 (1) Å. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93 Å for aromatic and CH and 0.96 Å for CH3 atoms. The Uiso values were constrained to be 1.5Ueq of the carrier atom for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
