A mixture of benzohydrazide (10 mmol) and nicotinaldehyde (10 mmol) was refluxed in ethanol (40 ml) for 2 h at 353K. After the solution had cooled down to room temperature yellow sediment appeared. The product was crystallized from a solution of methanol to yield yellow block-shaped crystals of the title compound (yield 78%). Anal. Calcd (%) for C13H11N3O (Mr = 225.25): C,69.32; H, 4.92; N, 18.65. Found (%): C, 69.21; H, 4.97; N, 18.76.
In the absence of significant
effects, Friedel pairs were averaged. The C—H and N—H H atoms were positioned with idealized geometry (N—H = 0.86 Å and C—H = 0.93 Å) and were refined using a riding model approximation with Uiso(H) = 1.2 Ueq(C, N).Acylhydrazones, as an example of
and their metal complexes have been widely studied due to their versatile applications in the fields of analytical and medicinal chemistry and biotechnology. These ligands, owing to their facile keto-enol and the availability of several potential donor sites, can coordinate with metals (Yin et al., 2008). We report here the synthesis and structure of the title compound. The molecular structure of the title compound is shown in Fig. 1. The hydrazone molecule crystallizes as an E isomer. In the there exist intermolecular N—H···N hydrogen bonds (Table 1). As seen in Fig. 2, the molecules are linked into one-dimensional extended chain structure.For related structures, see: Yin et al.
