In the title compound, C13H14N2O3S, the methyl 2-(3-formylthioureido)acetate fragment and the phenyl ring adopt an E configuration. The molecule exhibits an intramolecular N—H⋯O hydrogen bond, which completes a six-membered ring. The crystal packing is stabilized by intermolecular N—H⋯S contacts, generating a two-dimensional hydrogen-bonding network.

The title compound was synthesised according to a previously reported procedure (Hassan et al., 2008a). A colourless crystal, suitable for X-ray structuzre analysis was obtained by a slow evaporation from CH2Cl2 solution at room temperature (yield 73%).
H atoms of both C and N atoms were positioned geometrically and allowed to ride on their parent atoms, with Uiso=1.2Ueq (C) for aromatic 0.93 Å, Uiso = 1.2Ueq (C) for CH2 0.97 Å, and Uiso = 1.5Ueq (C) for CH3 0.96 Å. Hydrogen atoms attached to N were also positioned geometrically and allowed to ride on their parent atoms and with Uiso(H) = 1.2Ueq(N) for N–H 0.86 Å.
The title compound, I, is a methyl ester derivative of glycine thiourea analogoue to our previously reported molecules, methyl-2-(3-benzoylthioureido)acetate (II) (Hassan et al., 2009), ethyl-2-(3-benzoylthioureido)acetate (III) (Hassan et al., 2008a), propyl-2-(3-benzoylthioureido)acetate (IV) (Hassan et al., 2008b) and butyl-2-(3-benzoylthioureido)acetate (V) (Hassan et al., 2008c). Bond lengths and angles in the molecule are in normal ranges (Allen et al., 1987) and comparable to those of the benzoyl derivatives II, III, IV and V. The methyl acetate, [O2/O3/C9/C10/C11] plane is inclined to the phenyl ring, [C1—C6] (A), with a dihedral angle of 26.78 (18)° and this angle is smaller than that of compound (II) [73.4 (2)°]. The phenyl ring and the thiourea fragment, [S1/N1/N2/C9/C10/C11] (B), are essentially planar. In the methyl acetate group, the maximum deviation from the mean plane is 0.037 (2)Å for the atom O3. The dihedral angles of the fragments A/B and B/C are 11.17 (14)° and 20.21 (15)°, respectively, whereas the dihedral angle of the A/C fragments is 73.4 (2)°. There is an intramolecular hydrogen bond, N2—H2A···O1 which completes a six-membered ring (N2/H2A/O1/C9/N1/C10) (Fig. 1) and an intermolecular N1—H1A···S1 hydrogen bond (Table 1) which generates a two-dimensional hydrogen bonding network.

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 analogoue to our previously reported molecules, methyl-2-(3-benzoylthioureido)acetate (II) (Hassan et al., 2009), ethyl-2-(3-benzoylthioureido)acetate (III) (Hassan et al., 2008a), propyl-2-(3-benzoylthioureido)acetate (IV) (Hassan et al., 2008b) and butyl-2-(3-benzoylthioureido)acetate (V) (Hassan et al., 2008c). Bond lengths and angles in the molecule are in normal ranges (Allen et al., 1987) and comparable to those of the benzoyl derivatives II, III, IV and V. The methyl acetate, [O2/O3/C9/C10/C11] plane is inclined to the phenyl ring, [C1—C6] (A), with a dihedral angle of 26.78 (18)° and this angle is smaller than that of compound (II) [73.4 (2)°]. The phenyl ring and the thiourea fragment, [S1/N1/N2/C9/C10/C11] (B), are essentially planar. In the methyl acetate group, the maximum deviation from the mean plane is 0.037 (2)Å for the atom O3. The dihedral angles of the fragments A/B and B/C are 11.17 (14)° and 20.21 (15)°, respectively, whereas the dihedral angle of the A/C fragments is 73.4 (2)°. There is an intramolecular hydrogen bond, N2—H2A···O1 which completes a six-membered ring (N2/H2A/O1/C9/N1/C10) (Fig. 1) and an intermolecular N1—H1A···S1 hydrogen bond (Table 1) which generates a two-dimensional hydrogen bonding network.
