In the title compound, [Cu(C6F5COO)2(C4H4N2)]n, (I), the asymmetric unit contains one CuII cation, two anionic penta­fluoro­benzoate ligands and one pyrazine ligand. Each CuII centre is five-coordinated by three O atoms from three independent penta­fluoro­benzoate anions, as well as by two N atoms from two pyrazine ligands, giving rise to an approximately square-pyramidal coordination geometry. Adjacent CuII cations are bridged by a pyrazine ligand and two penta­fluoro­benzoate anions to give a two-dimensional layer. The layers are stacked to generate a three-dimensional supra­molecular architecture via strong inter­molecular C—H...F—C inter­actions, as indicated by the F...H distance of 2.38 Å.

Introduction top

Studies of coordination polymers have witnessed an upsurge in recent years due to their novel architectures, as well as their potential applications as functional materials (Hou et al., 2014; Freslon et al., 2014; Rybak et al., 2010; Deng et al., 2010). To date, a large number of coordination polymers have already been obtained through the assembly of various organic ligands and metal ions. However, the rational design and controllable prediction of prospective networks is still a great challenge, due to complicated factors such as the organic ligands, metal ions, solvent, temperature and counter-ions that could influence the ultimate structures (Manna et al., 2014; Lee et al., 2004). Recently, the utilization of mixed-ligand systems based on carboxyl­ates and N-donor ligands has proved to be an effective strategy to construct more intricate coordination polymers (Zhang et al., 2013; Wang et al., 2013). In dual-ligand systems, metal–carboxyl­ate architectures can be finely tuned by incorporating the different secondary N-donor linkers.

Taking all the above into account, we have successfully synthesized two new coordination polymers having the same coordination modes and structures, based on reactions of copper acetate, penta­fluoro­benzoic acid and pyrazine under different reaction conditions. Poly[[tris­(µ-penta­fluoro­benzoato-κ2O:O')bis­(µ-pyrazine-κ2N:N')copper(II)], (I), has been synthesized by a one-pot method with tri­ethyl­amine in ethanol. The same compound, denoted (II), has been obtained under hydro­thermal conditions without tri­ethyl­amine. In this paper, we report mainly the structural characterization of (I), and compare the two reaction pathways.

Synthesis and crystallization top

For the preparation of the (I), Cu(CH3COO)2·H2O (0.040 g, 0.20 mmol), penta­fluoro­benzoic acid (0.083 g, 0.40 mmol) and pyrazine (0.016 g, 0.20 mmol) were mixed in ethanol (10 ml) and tri­ethyl­amine (0.06 ml) in a flask equipped with a condenser, and the mixture was heated at 353 K for 3 h. During this period, a blue precipitate formed. The reaction mixture was cooled to room temperature, the precipitate removed by filtration, and the blue solid washed with ethanol (6 ml) and then dried under vacuum. The crude product was dissolved in di­methyl­formamide (12 ml) and the solution was layered with ethanol. Blue block-shaped crystals formed after 7 d (yield 0.067 g, 60% based on Cu2+). Analysis, calculated for C18H4CuF10N2O4: C 38.21, H 0.71, N 4.95%; found: C 38.14, H 0.80, N 5.03%.

For the preparation of (II), a mixture containing Cu(CH3COO)2·H2O (0.040 g, 0.20 mmol), penta­fluoro­benzoic acid (0.083 g, 0.40 mmol) and pyrazine (0.016 g, 0.30 mmol) in water (10 ml) was sealed in a Teflon-lined autoclave and heated under autogenic pressure to 358 K for 3 d and then allowed to cool to room temperature at a rate of 1 K h-1. Blue block-shaped crystals were obtained and these were collected by filtration, washed several times with distilled water and dried in air (yield 0.061 g, 55% based on Cu2+). Analysis, calculated for C18H4CuF10N2O4: C 38.21, H 0.71, N 4.95%; found: C,38.38, H 0.75, N 4.89%.

Results and discussion top

X-ray crystallographic analysis revealed that (I) crystallizes in the triclinic space group P1 with the molecule residing on a general position (Fig. 1). The relevant asymmetric unit consists of one crystallographically independent CuII centre, three penta­fluoro­benzoate anions (C6F5COO-) and two pyrazine ligands. The CuII cation is in an approximately square-pyramidal coordination environment, in which the equatorial plane is composed of two N atoms from two pyrazine ligands and two O atoms from two independent penta­fluoro­benzoate anions, while one O atom from a different penta­fluoro­benzoate anion occupies the apical position. Each CuII centre is five coordinated by three O atoms (O1 and O3, with O2 in the apical position) from three different penta­fluoro­benzoate anions (Table 2). Of the three independent Cu—O distances (Table 2), the apical Cu1—O2 distance is longer than the others, and it is especially longer than the two Cu—N distances. The angles among the two O atoms (O1 and O3) and two N atoms (N1 and N2) with Cu1 indicate that these five atoms are approximately located in an equatorial plane. The angles involving atom O2 (located at the apical position) and the equatorial plane (Table 2) indicate an approximately square-pyramidal coordination geometry. This coordination geometry of the five-coordinated CuII cation has been reported previously in recent years (Kennedy et al., 2014; Tjioe et al., 2011; Boonmak et al., 2009; Cui et al., 2008).

The penta­fluoro­benzoate anion coordination mode of µ3-η1:η2 is found in the crystal structure. The C6F5COO- group bridges two CuII cations; the carboxyl­ate group at C17 is monondentate, while that at C18 is bidentate-chelating to the CuII cations. The two carboxyl­ate groups of the penta­fluoro­benzoate anions coordinate two CuII cations to form a Cu–C6F5COO- chain, with a Cu1···Cu2 distance of 4.8046 (9) Å. Consequently, a one-dimensional linear chain is formed (Fig. 2). The Cu···Cu distance is longer than twice the sum of the van der Waals radius of copper (2.8 Å; Bondi, 1964), suggesting that there are no significant metal–metal inter­actions.

The pyrazine ligands connect adjacent CuII cations to form a one-dimensional linear chain, with a Cu1···Cu2 distance of 6.9047 (9) Å (Fig. 3). Obviously, the two kinds of one-dimensional chain cross each other by sharing CuII cations, generating a two-dimensional sheet. A schematic diagram of the two-dimensional polymeric layer is shown in Fig. 4. Adjacent two-dimensional layers are linked by inter­molecular C—H···F—C inter­actions between pyrazine H atoms and the F atoms of the penta­fluoro­benzoate anions, constructing a three-dimensional supra­molecular framework (Fig. 5).

From a thermodynamic point of view, the C—F bond is exceptionally strong, which is one of the reasons for the unique nature of fluorinated compounds. Incorporation of F atoms can lead to high stability, but also to a distinctly altered reactivity of fluorinated compounds compared with their nonfluorinated counterparts. For fluoro­aromatic compounds, C—H···F—C inter­actions, although weak, contribute significantly to regulating the arrangement of organic molecules in the crystalline state and to stabilizing the secondary structure of biomolecules such as DNA. The sum of the van der Waals radii of fluorine and hydrogen is about 2.67 Å. Consequently, an F···H distance up to 2.9 Å is considered as a C—H···F—C inter­action. The C—H···F angles [In (I)?] range from 70 to 180°, and such a wide range suggests weak inter­actions (Reichenbächer et al., 2005). In (I), the shortest F···H distance is 2.38 Å and the corresponding C—H···F angle is 144°. These results indicate the existence of strong C—H···F—C inter­actions in (I). Compared with (I), compound (II) has a shorter H···F distance of 2.37 Å and the C—H···F angle is 141°.

In order to investigate the function of tri­ethyl­amine, two different experiments were carried out in ethanol under one-pot conditions, the first including the addition of tri­ethyl­amine and the second with no tri­ethyl­amine. After 10 d, blue-block crystals formed in the former, but no crystals appeared in the latter. So tri­ethyl­amine, as a weak organic base, deprotonates C6F5COOH to C6F5COO-, and plays an important role in assisting crystal formation and controlling crystal size (Nordin et al., 2014; Tanaka & Ajiki, 2005; Klein et al., 2004).

It has been demonstrated previously that CuII can be easily hydro­thermally converted into CuI in the presence of different types of aromatic species (Chen & Tong, 2007; Lu, 2003). We expected that a CuI compound could be obtained under hydro­thermal conditions in our experiment. Nevertheless, the result demonstrated that CuII had not been reduced to CuI. Further studies of the effects of solvent and temperature on the formation of diverse CuI compounds under hydro­thermal conditions are in progress in our laboratory. Comparing the two reaction pathways, we think the hydro­thermal method has more advantages than the one-pot reflux method, firstly because the use of water as solvent is environmentally sound and a low-cost method, and secondly because, by virtue of high temperature and pressure, novel crystal structures and topologies can appear.

In summary, two similar structures have been obtained under different reaction conditions, indicating that the title compound is a stable structure with a five-coordinated CuII cation. Moreover, the results show that C—H···F—C inter­actions may play an important role in the formation of new supra­molecular structures, and can be utilized in crystal design and engineering.

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 > 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.

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.
