The title complex, [Cd(C14H11N2O4)2(C5H5N)2], exhibits crystallographic twofold symmetry. The CdII atom is located on the twofold rotation axis and reveals a slightly distorted octa­hedral coordination defined by four atoms (N2O2) from two symmetry-related chelate ligands and two pyridine N atoms. Intra­molecular O—H⋯O and N—H⋯O hydrogen bonds stabilize the mol­ecular conformation while inter­molecular O—H⋯O hydrogen bonding links mol­ecules into a triad, generating a helix along the threefold screw axis.

Comment top

Metal complexes with aroylhydrazine ligands are of increasing attention due to their interesting chemical activities (John et al. 2006; Dou et al., 2006). However, the research on the compounds with symmetrical diaroylhydrazine ligands was limited (Bernhardt et al., 2005; Chen et al., 2007). As an extension of our work on the structural characterization of these compounds, the title complex, (I), is synthesized and characterized by X-ray structure analysis. The complex (I) exhibits a twofold rotation symmetry. It comprises of one CdII atom at special position at the twofold rotation axes coordinated by two ligands and two pyridines (Fig. 1 and Table 1). Each ligand acts as the bidentate via the iminoacyl groups forming two five-membered rings around metal ion with the dihedral angle of 59.71 (4)°.

Intramolecular O4—H4···O3 and N2—H2···O2 hydrogen bonds stabilizes the molecular conformation. There is also an intermolecular hydrogen bond O—H···O hydrogen bond [ 2.639 (3) Å] (Table 2) assembling three molecules into a triad, that is a basic structural element of a helix along [0 0 1] direction (Fig. 2).

Experimental top

The solution of Cd(NO3)24H2O (0.123 g, 0.4 mmol) in methanol (10 mL) was added to the mixture of 1,2-disalicyloylhydrazine (0.054 g, 0.2 mmol) and sodium hydroxide (0.032 g, 0.8 mmol) in pyridine (10 mL). A colourless solution was generated after stirring for two hours at room temperature. The solution was allowed to stand for 2 weeks, whereupon white block crystals were obtained. Yield: 0.058 g, 77%. m. p.> 573 K. Anal. for C38H32CdN6O8: Calc. C, 56.08; H, 3.93; N, 10.33; Found: C, 56.54; H, 3.71; N, 10.54%. The No. of CCDC: 686345.

All H atoms were placed in geometrically idealized positions and treated as riding on their parent atoms with C(sp2 hybrid)-H distances of 0.93Å (Uiso(H)=1.2Ueq(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.
