In the title compound, [Co(C8H4O4)(C5H8N2)2]n, each cobalt(II) ion is coordinated by two N and two O atoms in a distorted tetra­hedral geometry. The isophthalate ligands bridge the metal ions to form polymeric zigzag chains extending along the b axis. Weak C—H⋯O inter­actions contribute to the crystal packing stability.

Supporting information


Comment top

In the title compound (Fig. 1), the cobalt(II) ion is coordinated by two N and two O atoms in a distorted tetrahedral geometry. The values of bond distances and angles (Table 1) agree well with those observed in [Co(isophthalato)(1-H-imidazole)2] (Song, et al., 2007). Each isophthalate dianion acts as a bidentate ligand to bridge two cobalt(II) atoms through the monodentate carboxylate groups, building a zigzag chain structure along the b axis (Fig. 2). The metal-metal distance across the polymer backbone is 9.665 (7) Å. Weak C—H···O hydrogen interactions contribute to the crystal packing stability (Table 2).

Experimental top

The reaction of CoCl2.6H2O (1.19 g, 5 mmol) with isophthalic acid (0.83 g, 5 mmol) in a water/ethanol (3:1 v/v) solution (40 ml) at 363 K for 30 minutes produced a blue solution, to which 1-ethylimidazole (0.84 g,10 mmol) was added. The reaction solution was kept at room temperature after stirring for an hour at 333 K. Pink crystals were obtained after a few days on slow evaporation of he solvent.

Refinement top

H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93-0.97 Å and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms.

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.
