In the title compound, C7H11NO4, which is an example of a push–pull alkene, a network of N—H⋯O and C—H⋯O interactions helps to establish the The investigated crystal turned out to be a non-merohedral twin with a ratio of twin components of 0.442 (3):0.558 (3). Two pairs of independent molecules (Z′ = 4) are linked by intermolecular N—H⋯O hydrogen bonds, forming independent chains; the chains are connected via intermolecular C—H⋯O contacts, building a three-dimensional network.

To dimethyl 3-methoxymethylenemalonate (1.74 g, 10 mmol) in methanol (10 ml), an aqueous solution of methylamine (12 mmol) was added dropwise (amount according to concentration and density) over a period of 30 min with stirring. The slightly warmed mixture was stirred overnight at room temperature. The reaction mixture was then briefly heated to reflux (ca. 20 min). After ensuring that no starting derivative remained (thin-layer
Silufol 254, Kavalier Czechoslovakia; chloroform-methanol 10:1 v/v, detection UV light 254 nm), the reaction mixture was evaporated on a vacuum evaporator and chromatographed on silica gel (eluent dichloromethane-methanol 10:1 v/v). Obtained product was recrystallized from minimal amount of chloroform and n-hexane mixture in refrigerator.The solid phase mid-IR vibrational spectrum was recorded with a Nicolet model NEXUS 470 FTIR spectrometer at room temperature. The measurement was performed after mixing the powdered sample with KBr into a pellet.

Olefinic and amino H atoms were positioned geometrically and allowed to ride on their corresponding parent atoms at distances of 0.93 and 0.86 Å, respectively, with Uiso(H) = 1.2Ueq(C,N). Methyl H atoms were located in a difference Fourier map and included in the model as a rigid rotating group, with C—H distance of 0.96 Å and with Uiso(H) = 1.5Ueq(C).
The investigated crystal was a non-merohedral twin. Two orientation matrices could be determined and the
was derived using the program TWINLAW (Bolte, 2004):h(twin) = (1.00 * h) + (0.00 * k) + (0.00 * l)
k(twin) = (-0.15 * h) + (-1.00 * k) + (0.00 * l)
l(twin) = (-0.16 * h) + (0.00 * k) + (-1.00 *l).
For the
the reflection data file was modified using the program HKLF5 (Bolte, 2004). The contribution of the minor twin component refined to 0.442 (3).Data collection: CrysAlis CCD (Oxford Diffraction, 2006); cell

Experimental. face-indexed (CrysAlis RED; Oxford Diffraction, 2006). 96 rigid bond restaints (DELU) were used in the refinement because the data to parameter ratio is low due to four independent molecules in the twinned structure. |
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, C7 H11 N O4, belongs to the so-called push-pull olefins. Push-pull alkenes are substituted ethylenes containing electron-donor groups (D) at one end and electron-acceptor groups (A) at the other end of the general formula D1D2C=CA1A2. These compounds very often contain alkoxy, amino, alkylamino, dialkylamino or (hetero)aryl groups as electron-donor groups and cyano, acetyl, alkylester, methylsulfonyl or NO2 groups as electron-acceptor groups. They are useful as starting reactants or intermediates for a lot of pharmaceutical, polymer and other syntheses (Cook, 1969; Dyke, 1973). Mainly enamines are frequently used as reactants or intermediates in chemical syntheses of drugs, polymers and dyes (Bouzard, 1990). But also alkoxymethylenes are often used in organic synthesis (Freeman, 1981).
Chemical and physical properties of the title related structures were recently discussed (Gróf et al., 2008 and literature cited therein).
The study of a similar compound, dimethyl 2-(aminomethylene)malonate, (Gróf et al., 2008) revealed that this structure exists in the solid phase as EZ conformer (E denotes away from C=C double bond orientation of the carbonyl oxygen in trans position; Z denotes towards to C=C double bond orientation of the carbonyl oxygen in cis position). The title compound exists in the solid phase as ZZa conformer (a denotes anti orientation of the methylamino group, e.g. away from the C=C double bond orientation).
The molecules I and II, and molecules III and IV of the title compound (Fig.1) show pseudo translation (Kálmán & Argay, (1998).
