In the title compound, C11H12N2O3S, the methyl acetate and benzoyl groups adopt a cis-trans configuration with respect to the thiono S atom across the C—N bonds. An intramolecular N—H⋯O hydrogen bond is observed. In the crystal packing, molecules are linked by intermolecular N—H⋯S and C—H⋯O hydrogen bonds to form a two-dimensional network lying parallel to (101).

The title compound was synthesized according to a previously reported method (Hassan et al., 2008a). Yellowish crystals, suitable for X-ray analysis, were obtained by slow evaporation of a CH2Cl2 solution at room temperature (yield 73%).
H atoms were positioned geometrically [N-H = 0.86 Å and C-H = 0.93-0.97 Å] and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq (C,N) and 1.5Ueq(Cmethyl).

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. |

The title compound, (I), is a methyl ester derivative of glycine thiourea analogous to our previously reported ethyl-2-(3-benzoylthioureido)acetate (II) (Hassan et al., 2008a), propyl-2-(3-benzoylthioureido)acetate (III) (Hassan et al., 2008b) and butyl-2-(3-benzoylthioureido)acetate (IV) (Hassan et al., 2008c). The methyl acetate fragment and the benzoyl group adopt a cis-trans configuration, respectively, with respect to the thiono S atom across the C—N bonds (Fig 1). The dihedral angle between the phenyl ring (C1–C6) and the central fragment (S1/N1/N2/C8/C9) is 20.12 (19)°. The bond lengths (Allen et al., 1987) and angles in the molecule are in normal ranges and comparable to those of (II), (III) and (IV). The methyl acetate group (O2/O3/C9/C10/C11) is planar, with a maximum deviation of 0.023 (3) Å for atom O3. The dihedral angle between the phenyl ring and the methyl acetate group is 73.4 (2)°. An intramolecular N2—H2A···O1 hydrogen bond (Table 1) forms a pseudo-five-membered N2/H2A/O1/C7/N1/C8 ring.
Intermolecular N1—H1A···S1 and C9—H9A···O2 hydrogen bonds (Table 1) link the molecules into a two-dimensional network parallel to the (101) (Fig 2).
