Methyl hydrazinecarboxylate (0.90 g, 0.01 mol) was dissolved in ethanol- dilute HCl and single crystals suitable for X-ray analysis were obtained by slow evaporation at room temperature (m.p. 463–465 K).
O- and N-bound H atoms were located in a difference map and were refined with O-H and N2-H2 distances restrained to 0.85 (2) Å and 0.87 (1) Å, respectively. The methyl H atoms were disordered over two orientations and their occupancies were initially refined and later fixed at 0.75 and 0.25, with C-H = 0.96 å and Uiso(H) = 1.5Ueq(C).

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. |

Benzaldehydehydrazone derivatives have received considerable attention for a long time due to their pharmacological activity (Parashar et al., 1988) and their photochromic properties (Hadjoudis et al., 1987). The title compound is an important intermediate in the synthesis of benzaldehydehydrazone derivatives. We report here the crystal structure of the title compound (Fig. 1).
In the cation, atoms O1, O2, N2, C1 and C2 are coplanar (r.m.s. deviation 0.029 Å) and atom N1 deviates by 0.260 (2) Å from the C1/C2/O1/O2/N2 plane. The bond lengths and angles in the organic cation are comparable to those in a related structure (Song et al., 2003).
The molecules are linked into a two-dimensional network parallel to the bc plane by N–H···O, N—H···Cl and O—H···Cl hydrogen bonds involving the water molecule and chloride ions (Table 1 and Fig.2).
