Abstract top

The asymmetric unit of the title compound, C11H9N3O2, contains two independent molecules: the dihedral angles between the pyridine ring and the furyl ring are 17.00 (16) and 34.12 (15)°. The crystal structure involves intermolecular C-H...O, N-H...N and N-H...O hydrogen bonds.

Comment top

The chemistry of Schiff bases has attracted a great deal of interest in recent years. These compounds play an important role in the development of various proteins and enzymes (Kahwa et al., 1986; Santos et al., 2001). As part of our in the study of the coordination chemistry of Schiff bases, we synthesized the title compound and determined its crystal structure.

The molecular structure is shown in Fig.1. Each molecule is not planar, making the dihedral angle of 17.00 (16) and 34.12 (15)° between pyridine and furyl rings, respectively. In the crystal structure, molecules are linked through intermolecular C—H···O, N—H···N and N—H···O hydrogen bonds, forming a network.

Experimental top

Pyridine-4-carboxylic acid hydrazide (1 mmol, 0.137 g) was dissolved in anhydrous ethanol (15 ml), The mixture was stirred for several minutes at 351 K. Furan-2-carbaldehyde (1 mmol, 0.96 g) in ethanol (8 mm l) was added dropwise and the mixture was stirred at refluxing temperature for 2 h. The product was isolated and recrystallized from methanol. Pink single crystals of (I) was obtained after 3 d.

Refinement top

All H atoms were positioned geometrically and refined as riding with C—H = 0.93(aromatic) and N—H = 0.86Å, with Uiso(H) = 1.2Ueq(CH, NH).

Special details top

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.
