Abstract top

The asymmetric unit of the title compound, C24H24N4O8·2C3H7NO, contains half of the centrosymmetric molecule of dimethyl 2,5-bis[2-(2-hydroxybenzoyl)hydrazino]cyclohexa-1,4-diene-1,4-dicarboxylate and one dimethylformamide solvent molecule. There is a dihedral angle of 61.7 (1)° between the central and two outer rings. The crystal structure involves N-H...O, O-H...O and C-H...O hydrogen bonds.

Comment top

Aroylhydrazone and their metal complexes have been actively investigated for many years due to their wide spread applications in the fields of coordination chemistry (Milway et al., 2004), bioinorganic chemistry (Patole et al., 2003) and catalytic chemistry (Pouralimardan et al., 2007). As an extension of our work on the structural characterization of aroylhydrazone derivatives (Liu et al., 2005; Kang et al., 2007), the title compound, (I), has been synthesized and structurally characterized.

In (I) (Fig. 1), the C8—C9 bond length of 1.354 (5) Å indicates that centrosymmetric aroylhydrazone moiety exists in the enol form with the formation of N2—H2···O4 hydrogen bond (Table 1). The central ring is essentially planar with the mean deviation of 0.0095 Å. The dihedral angle between the central ring and benzene ring C2—C7 is 61.7 (1)°. The intermolecular N—H···O hydrogen bonds and weak C—H···O interactions (Table 1) contribute to the crystal packing stability.

Related literature top

The crystal structures of cobalt and nickel complexes with the related aroylhydrazone derivative have been reported by Milway et al. (2004) and Liu et al. (2005), respectively. The crystal structure of 3-hydroxy-N-[phenyl(2-pyridyl)methylene]- 2-naphthohydrazide was reported by Kang et al. (2007). For the catalytic and biological activities of aroylhydrazones, see: Pouralimardan et al. (2007) and Patole et al. (2003), respectively.

Experimental top

The mixture of dimethyl-1,4-cyclohexanedione-2,5-dicarboxylate (2.28 g, 10 mmol) and salicylhydrazide (3.04 g, 20 mmol) in ethanol (30 ml) were refluxed for 6 h, and then the yellow precipitate was collected, washed with ethanol and dried in vacuo (yield 92%). The yellow solid was dissolved in DMF, then crystals suitable for X-ray diffraction were obtained after three weeks (m.p. 480–482 K). Elemental analysis: calcd. for C30H38N6O10: C 56.07, H 5.91, N 13.07%; found: C 56.15, H 5.59, N 13.13%.

Refinement top

All H atoms were placed geometrically (O—H 0.82 Å, N—H 0.86 Å, C—H 0.93–0.97 Å) and treated as riding on their parent atoms, with Uiso(H) = 1.2–1.5Ueq(parent atom).

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 > 2sigma(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.
