In the title compound, C14H16N6O6·C2H6O·H2O, both substituents of the benzene ring are approximately planar with maximum deviations from the mean plane of 0.0561 (12) (an imine N atom) and 0.1419 (11) Å (a methoxy O atom). The substituents are tilted out of the plane of the benzene ring by 64.48 (4) and 70.08 (5)°, respectively. In the crystal, molecules form centrosymmetric dimers associated via pairs of N—H⋯O hydrogen bonds. The dimers are linked via the water and ethanol molecules, forming two-dimensional hydrogen-bond networks lying parallel to (100).

In a round bottom flask, dimethylether-1,3-benzodiketodicarboxylic acid (0.02 mol, 0.51 g) was dissolved in 5 ml methanol. Drops of semicarbazide chloride (0.04 mol, 0.44 g) dissolved in ethanol (5 ml) were then added. The reaction mixture was refluxed for 30 min. The precipitate (0.44 g )formed after 24 h was filtered. The precipitate was then dissolved in ethanol at room temperature. After few days, colorless crystals (m.p. 120–121°C) were formed by slow evaporation.
C-bound H atoms were placed in calculated positions with C—H 0.93 Å for aromatic, 0.97 Å for CH2 and 0.96 Å for CH3 hydrogens and were refined as riding on their parent atoms, with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(C) for methyl H atoms. NH H atoms were placed in calculated positions with N—H 0.86 Å and refined in riding mode with Uiso(H) = 1.2 Ueq(N). The H-atoms bonded to the O atom of the water molecule were found from difference Fourier map and their coordinates were refined independently with Uiso(H) = 1.5 Ueq(O). The H-atom bonded to the O atom of the ethanol molecule and the NH2 H atoms were refined freely.

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. |

It has been reported previously that arylketodicarbonicacid derivatives possess antiinflammatory activity (Ismatov et al., 1991, Ismatov et al., 1998, Ismatov et al., 2001). We report herein the X-ray crystallographic study of a disemicarbazonodimethylether-1,3-benzenediketodicarbonic acid monohydrate ethanol solvate.
The asymmetric unit of the title compound, C14H16N6O6.C2H6O.H2O, contains a disemicarbazonodimethylether-1,3-benzenediketodicarbonic acid (DBA), an ethanol and a water molecule as shown in Fig. 1. In the DBA molecule the planes of the substituent fragments (C1/C7/C8/N1/N2/O1/O2 and C3/C11/C12/N4/N5/O4/O5) are tilted out of the mean plane of the benzene ring by 64.48 (4)° and 70.08 (5)°, respectively.
In the crystal structure (Fig. 2), DBA molecules form centrosymmetric pair associates via N2—H···O3 and N5—H···O3 H-bonds and the associates are linked via H-bonds by water (O1W—H1···O5, O1W—H2···O6, N6—H···O1W) and ethanol (N6—H···O7, N3—H3···O7,O7—H7···O2) molecules forming two-dimensional networks parallel to the (100) plane (Table 1).
