In the title compound, C17H16N2O5, the dihedral angles between the central urea [N—C(=O)—N] fragment and its attached benzene rings are 20.20 (14) and 24.24 (13)°; the dihedral angle between the aromatic rings is 42.1 (1)°. The molecular conformation is consolidated by two intramolecular N—H⋯O hydrogen bonds, which both generate S(6) rings. In the crystal, inversion dimers linked by pairs of C—H⋯O interactions generate R22(14) loops. The dimers are linked by further C—H⋯O interactions into (011) sheets.

A solution of 2-(methoxycarbonyl)benzoic acid (100 mg, 0.56 mmol), DPPA (0.194 ml, 0.90 mmol) and Et3N (0.127 ml, 0.90 mmol) in toluene (3 ml) was refluxed for 4 h. After cooling to room temperature, the reaction mixture was concentrated. The residue was purified by
using EtOAc-Hexane (1:9 v/v) as to give yellow blocks with yield = 40% and m.p. = 411 K.All H atoms could be located in a difference Fourier map. However, they were placed in calculated positions with C–H = 0.93–0.96 Å; N—H = 0.86 Å, and refined as riding on their parent atoms with Uiso(H) = 1.2 Ueq for aromatic, C—H, N–H and Uiso(H) = 1.5 Ueq for methyl. Two outlier (1 0 0) and (0 2 0) was omitted in the last cycles of refinement.
Urea derivatives are very interesting reagents due to their useful properties and important medical and biological applications, such as insecticidal, fungicidal, herbicidal, anti-infectives and plant-growth regulating activities (Abad et al., 2004; Chen et al., 2005, Batra et al., 2006), especially cytokinin activity (Wang et al., 2001; Ricci et al., 2005). Symmetrical disubstituted ureas generally form a polar hydrogen-bond chain, with anti NH donors and carbonyl O-atom acceptors in a bifurcated motif. As part of our studies in this area, the title compound C17H16N2O5 was synthesized and its
is reported in the present work.The molecular structure of the title compound, a symmetrical urea derivative, is displayed in Fig. 1. This molecule is build up from two methyl benzoate linked through N–C(=O)–N fragment but not symmetric. The dihedral angle between the two phenyl rings (C3 to C8) and (C10 to C15) is of 42.1 (1)°.
In the crystal, the
is stabilized by two intramolecular N—H···O hydrogen bonds and each molecule is linked to its symmetric by two intermolecular C—H···O hydrogen bonds to form centrosymmetric dimers as shown in Fig.2.For the medical and biological activities of urea derivatives, see: Abad et al. (2004); Chen et al. (2005); Batra et al. (2006). For cytokinin activity, see: Wang et al. (2001); Ricci et al. (2005).

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. |

Urea derivatives are very interesting reagents due to their useful properties and important medical and biological applications, such as insecticidal, fungicidal, herbicidal, anti-infectives and plant-growth regulating activities (Abad et al., 2004; Chen et al., 2005, Batra et al., 2006), especially cytokinin activity (Wang et al., 2001; Ricci et al., 2005). Symmetrical disubstituted ureas generally form a polar hydrogen-bond chain, with anti NH donors and carbonyl O-atom acceptors in a bifurcated motif. As part of our studies in this area, the title compound C17H16N2O5 was synthesized and its crystal structure is reported in the present work.
The molecular structure of the title compound, a symmetrical urea derivative, is displayed in Fig. 1. This molecule is build up from two methyl benzoate linked through N–C(=O)–N fragment but not symmetric. The dihedral angle between the two phenyl rings (C3 to C8) and (C10 to C15) is of 42.1 (1)°.
In the crystal, the molecular conformation is stabilized by two intramolecular N—H···O hydrogen bonds and each molecule is linked to its symmetric by two intermolecular C—H···O hydrogen bonds to form centrosymmetric dimers as shown in Fig.2.
