5-(2-Methoxy­benz­yl)-4-(2-methoxy­phen­yl)-4H-1,2,4-triazol-3-ol

Abstract

In the mol­ecule of the title compound, C17H17N3O3, the triazole ring is oriented at dihedral angles of 88.09 (3) and 83.72 (3)° with respect to the 2-methoxy­benzyl and 2-methoxy­phenyl rings, respectively. The dihedral angle between the 2-methoxy­benzyl and 2-methoxy­phenyl rings is 52.95 (3)°. In the crystal structure, inter­molecular N—H(...)O hydrogen bonds link the mol­ecules into centrosymmetric dimers. There is a π–π contact between the 2-methoxy­phenyl rings [centroid–centroid distance = 3.811 (3) Å].

Comment

Substituted triazole derivatives display significant biological activities including antimicrobial (Holla et al., 1998), analgesic (Turan-Zitouni et al., 1999), antitumor (Demirbas et al., 2002), antihypertensive (Paulvannan et al., 2000) and antiviral (Kritsanida et al., 2002) activities. The biological activity is closely related to the structure, possibly being due to the presence of the —N—C—S unit (Omar et al., 1986). We are interested in the syntheses and biological activities of the aryloxyacetyl hydrazide derivatives and report herein the synthesis and crystal structure of the title compound.

In the molecule of the title compound (Fig. 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges, and they are comparable with those observed in related structures (Öztürk et al., 2004a,b). In the triazole ring, the N2=C1 [1.2960 (16) Å] bond has double bond character. Rings A (N1/N2/N3/C1/C2), B (C4-C9) and C (C11-C16) are, of course, planar and the dihedral angles between them are A/B = 88.09 (3)°, A/C = 83.72 (3)° and B/C = 52.95 (3)°.

In the crystal structure, intermolecular N-H···O hydrogen bonds (Table 1) link the molecules into centrosymmetric dimers (Fig. 2), in which they may be effective in the stabilization of the structure. The π—π contact between the 2-methoxyphenyl rings, Cg1···Cg1i [symmetry code: (i) -x, 2 - y, -z, where Cg1 is the centroid of the ring C (C11-C16)] may further stabilize the structure, with centroid-centroid distance of 3.811 (3) Å.

Experimental

The synthesis of the title compound was carried out by refluxing a solution of 4-(2-methoxyphenyl)-1-(2-(2-methoxyphenyl)acetyl)semicarbazide (3.29 g, 10 mmol) in NaOH (2M) for 5 h. Crystals suitable for X-ray analysis were obtained by recrystallization from an aqeous ethanol solution at room temperature (yield; 79%; m.p. 444–445 K).

Refinement

H3N atom (for NH) was located in difference synthesis and refined isotropically [N-H = 0.890 (17) Å and Uiso(H) = 0.029 (4) Å2]. The remaining H atoms were positioned geometrically, with C-H = 0.95, 0.99 and 0.98 Å for aromatic, methylene and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

Special details

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.
