Abstract

The asymmetric unit of the title compound, C9H11N3O2, contains two mol-ecules (A and B), which exist in Z conformations with respect to their C=N double bond. The dihedral angles between the benzene ring and the pendant hy-droxy-carbamimidoyl and acetamide groups are 28.58 (7) and 1.30 (5)°, respectively, in mol-ecule A and 25.04 (7) and 27.85 (9)°, respectively, in mol-ecule B. An intra-molecular N-H⋯N hydrogen bond generates an S(6) ring in both mol-ecules. Mol-ecule A also features an intra-molecular C-H⋯O inter-action, which closes an S(6) ring. In the crystal, the mol-ecules are linked by N-H⋯O, N-H⋯N, O-H⋯O, O-H⋯N, C-H⋯O and C-H⋯N hydrogen bonds and C-H⋯π inter-actions, generating a three-dimensional network.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100 (1) K.
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.
