The title compound, [Co(H₂O)₆](C₁₆H₁₂O₆)·H₂O, is composed of one 4,4′-(1,2-dihydroxyethane-1,2-diyl)dibenzoate anion lying on an inversion center, one [Co(H₂O)₆]²⁺ dicationic complex and a solvent water molecule located on mirror planes. In the crystal, a chain is constructed via O—H⋯O hydrogen bonds involving the carboxylate and hydroxyl groups of the organic anion; the chains are further connected into a three-dimensional framework by additional O—H⋯O hydrogen bonds between the [Co(H₂O)₆]²⁺ cations, solvent water molecules and the anions.

Comment top

Metal-organic coordination polymers have been greatly developed in recent years due to their captivating structure (Kondo et al., 2004; Fan et al., 2005) and potential applications as functional materials in electronic (Lin et al., 2004), magnetic (Laborda et al., 2004; Liang et al., 2000; Fei et al., 2005) and optical (Zhang et al., 2006) fields. Thus, we choose the ligand 4,4'- (1,2-dihydroxyethane-1,2-diyl)dibenzoate and Co(NO3)₂ under hydrothermal conditions to obtain new metal-organic complex, We report here the synthesis and structure of the title compound.

As shown in Figure 1, the title compound [Co(H₂O)₆][C₁₆H₁₂O₆].H₂O is composed of one 4,4'-(1,2-dihydroxyethane-1,2-diyl)dibenzoate anion lying on inversion center, one [Co6H₂O]²⁺ dicationic complex and a solvent water molecule locating on mirror planes. The Co^II ion is coordinated by six water molecules in an octahedral geometry. The hydroxyl groups of the 4,4'-(1,2-dihydroxyethane-1,2-diyl)dibenzoate anion are oriented such the the H atoms are directed away from the plane of the benzene ring. In the crystal, a one-dimensional chain is constructed via O—H···O hydrogen bonds interactions involving the carboxylate and hydroxyl groups of the organic anion, which was further connected into a three-dimensional framework by additional O—H···O hydrogen bonds formed by [Co(H₂O)₆]²⁺ cations, solvent water molecules and the anions.

Experimental top

A mixture of 4,4'-(1,2-dihydroxyethane-1,2-diyl)dibenzoate(0.5 mol, 0.15 g) and Co(NO₃)₂ (0.5 mol, 0.14 g) in 30 ml of absolute ethanol was heated under reflux for 6 h in the presence of 1-2 drops of NaOH. The reaction mixture was cooled to room temperature for 2 h. The light-red crystal was filtered off and washed several times using absolute ethanol.

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.
