(Received 8 April 2011; accepted 20 May 2011; online 28 May 2011)

In the title coordination polymer, {[Co(C₃H₇COO)₂(H₂O)]·0.7H₂O}_n, the Co²⁺ cation is coordinated by four bridging butanoate anions and two bridging water molecules in a severely distorted octahedral geometry. The Co²⁺ cations are linked by means of bridging ligands into polymeric chains along [010]. These chains are further connected to each other through hydrogen bonds involving partially occupied disordered water molecules; thus, sheets parallel to (001) are formed. One of the positions of disordered water O atom lies on a twofold axis. Two atoms of the aliphatic chain of one of the butanoate anions are disordered over two positions each.

Comment top

Cobalt carboxylates are of great importance because of their application in homogeneous oxidation catalysis (Gates, 1992; Parshall & Ittel, 1992; Partenheimer, 1995), and their interesting magnetic properties (Eremenko et al., 2009). Recently, we have reported on the crystal structure of the polymeric cobalt(II) propionate dihydrate, which was prepared by the reaction of cobalt(II) carbonate hydrate with aqueous propionic acid (Fischer et al., 2010). We found that the use of butyric acid instead of propionic acid leads to an analogous product, {[Co(C₃H₇COO)₂(H₂O)].0.7H₂O}_n (I). This salt, named as cobalt(II) butyrate 1.7-hydrate, is interesting for us as a starting reagent for the preparation of the mixed-valence cobalt carboxylates.

The crystal structure of the title compound contains one independent Co²⁺ cation coordinated by four O atoms of four bridging butyrates and two O atoms of bridging water molecules in a severely distorted octahedral coordination (Fig. 1). The cis-angles about the Co atom range from 80.77 (9) to 106.47 (9)°, the Co—O bond lengths are in the range of 2.027 (2) – 2.217 (2) Å; this data correlates with the angles and the distances in cobalt(II) acetate dihydrate with similar structure (Jiao et al., 2000) as well as isostructural cobalt(II) propionate dihydrate (Fischer et al., 2010). The structure of the title compound features infinite chains with composition _∞[Co(C₃H₇COO)_4/2(H₂O)_2/2] running along [010]. The Co···Co minimum distance in the chain is equal to 3.1436 (7) Å. The bridging butyrate groups adopt two coordination modes, monodentate and syn-syn bidentate. The bidentate group has C—O bonds of practically equal length, 1.253 (4) and 1.254 (4) Å, whereas monodentate group has different C—O bond lengths, 1.231 (4) and 1.293 (4) Å. The chains are connected to each other through O—H···O hydrogen bonds involving partially occupied disordered water molecules; as a result, the sheets parallel to the (001) plane are produced (Fig. 2). The O61 atom of disordered solvate water molecule occupies a special position on the twofold axis.

Experimental top

To a solution of butyric acid (8.8 g, 100 mmol) in water (50 ml), an excess of fresh cobalt(II) carbonate hydrate, CoCO₃.xH₂O (x=0.35–1.00), (8.0 g, approximately 60 mmol) was added. The reaction mixture was periodically stirred in ultrasonic bath at room temperature until the liberation of carbon dioxide ceased. The unreacted CoCO₃.xH₂O was removed by filtration, and the filtrate was allowed to stand at room temperature for slow evaporation. After a few days, red single crystals of the title compound suitable for X-ray diffraction study precipitated. Yield 82%.

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.
