In the title compound, [Cd(NO₃)₂(C₁₂H₁₂N₆)₂]_n, the Cd^II cation is located on an inversion center and is six-coordinated by four N atoms from four 1,3-bis[(1H-1,2,4-triazol-1-yl)methyl]benzene (L) ligands and two O atoms from two nitrate anions in a slightly distorted octahedral geometry. The ligands link different Cd^II ions into a ribbon-like structure along [001]. Two O atoms of the nitrate anion are disordered over two sets of sites with site occupancies of 0.575 (8) and 0.425 (8).

Comment top

In recent years, much attention has been paid to the use of nitrogen-containing ligands for constructing supramolecular coordination compounds. The reason is that the supramolecular coordination assemblies have not only a variety of architectures but also have potential applications as functional materials. Recently, a series of supramolcular complexes based on the 1,4-bis(1H-1,2,4-triazol-1-yl-methyl)-benzene ligand were reported (Meng et al., 2004). In this paper, we report the new title compound, synthesized by the reaction of 1,3-bis((1H-1,2,4-triazol-1-yl)methyl)benzene and cadmium dinitrate in an aqueous solution.

In the title compound, [Cd(NO3)₂(C₁₂H₁₂N₆)₂]_n, the eight-coordinated Cd^II ion is located on an inversion center and is in an octahedral environment defined by four N atoms from ligands forming the equatorial plane (distances Cd—N1 = 2.330 (2) Å and Cd—N4 = 2.328 (2) Å) and two O atoms from two nitrate anions lying on the polar axis with a Cd—O1 distance of 2.479 (5) Å (Figure 1, Table 1). An infinite ribbon-like structure running along [001] is built up by the cis-ligands linking these Cd^II ions (Figure 2).

Experimental top

The ligand L was synthesized following the reference method (Du et al.,2008). Synthesis of the title compound: L (0.120 g, 0.5 mmol) and Cd(NO3)₂ (0.152 g, 0.5 mmol) were dissolved in a mixed solution of 3 mL ethanol and 3 mL water. After stirring, the suspension was sealed in a 18 mL Teflon-lined autoclave and heated at 140 °C for 5 days. After slow cooling to room temperature, colorless block crystals were filtered and washed with distilled water (47% yield based on Cd).

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
