The title compound, [Cu2Fe3(C5H5)3(C2H3O2)(C6H4O2)3(C3H7NO)2], belongs to the classic dimeric paddle-wheel structure type. It is an unusual example in that it contains two different carboxyl­ate groups, viz. ferrocenecarboxyl­ate and acetate. With three ferrocenecarboxyl­ate groups and only one acetate group bridging the two Cu centres, a noncentrosymmetric mol­ecular arrangement results.

Comment top

The dimeric copper(II) carboxylates and their adducts, [Cu2(O2CR)2L2], have played a major role in copper(II) carboxylate chemistry (Agterberg et al., 1997; Moulton et al., 2003). The related complexes have received much attention because of their potential use as anti-inflammatory drugs (Demertzi et al., 2004; Weder et al., 2004). In addition, such complexes are good models for the investigation of the exchange interaction between paramagnetic centres in discrete molecules (Costa et al., 1998). The polarizability of the R group on the carboxylate has a vital relationship with the magnitude of the magnetic interaction (Porter & Doedens, 1984; Schlam et al., 2000). While the ferrocenyl unit itself always affects electron interactions in compounds, in this case it may help to probe the influence of the substituent R on the magnetic behaviour. Moreover, compounds containing ferrocenyl units always show some unusual properties and have potential applications in the field of materials science, such as molecular sensors (Beer, 1992), molecular magnets (Miller & Epstein, 1994) and nonlinear optical materials (Long, 1995). Dinuclear copper(II) complexes with two different kinds of carboxylate groups still remain rare, especially ones with bulky carboxylate groups like ferrocenecarboxylate (Churchill et al., 1985), which may be due to the existence of evident steric hindrance. We report here the synthesis and crystal structure of the title dimeric copper(II) carboxylate, (I), with ferrocenecarboxylate and acetate groups.

Only one noncentrosymmetric dimeric copper(II) carboxylate, Cu2{µ-[(CO)9Co33-CCO2)]}3[µ-(CH3CO2)][OC4H8]2 (Banares et al., 1985), has been reported to date, according to the Cambridge Structural Database (CONQUEST, Version 1.3, updated May 2007; Bruno et al., 2002). Thus, complex (I) represents the second example.

In complex (I), the asymmetric unit contains two crystallographically independent CuII ions, three ferrocenecarboxylate groups, one acetate group and two dimethylformamide (DMF) molecules. The two CuII centres are separated by 2.618 (28) Å, and each CuII centre has a square-pyramidal coordination environment, with four O atoms from three ferrocenecarboxylate groups and one acetate group in the basal plane, and an O atom from a DMF molecule in the apical position. As expected, the apical Cu—ODMF distances are notably longer than the basal ones between Cu and the O atoms from the carboxylate groups.

The novel character of (I) lies in its noncentrosymmetric structure type, which is still very rare in this classical kind of complex. In (I), there are three ferrocenecarboxylate groups and only one acetate group. The ferrocene substituents on the carboxylate ligands that are trans to each other are oriented to the same side of the Cu···Cu line, and the less bulky methyl substituent of the acetate ligand is located in the space between the two ferrocene units (Fig. 1). The arrangement of the ferrocenecarboxylate groups is therefore different from that in the centrosymmetric compound tetrakis(ferrocenecarboxylato)bis(tetrahydrofuran)copper(II) reported by Churchill et al. (1985), in which the four ferrocene units are arranged in a clockwise mode.

There is also a noticeable difference between the conformations of the coordination of the CuII and carboxylate O atoms of (I) and the Churchill complex. In the previously reported complex, the two CuII centres and the coordinated O atoms belonging to the same carboxylate group are nearly located in the same plane, with O—Cu—Cu—O torsion angles between them of -1.89 (30) and 0.83 (30)° for the two independent carboxylate groups. By contrast, in (I) the four corresponding torsion angles are distinctly larger: 15.01 (21), 14.43 (21), 14.04 (21) and 15.01 (19)°. The obvious variance may due to the different steric hindrance in the complexes. Perhaps as a result of the smaller steric hindrance, the O—Cu—Cu—O torsion angles of the other noncentrosymmetric dimeric copper(II) carboxylate (Banares et al., 1985) are also distinctly smaller than complex (I), with values ranging from -3.97 (29) to 4.57 (29)°.

Experimental top

For the preparation of (I), ferrocenecarboxylic acid (0.046 g, 0.02 mmol) and NaHCO3 (0.017 g, 0.02 mmol) were dissolved in a mixture of CH3OH (10 ml) and dimethylformamide (DMF; 2 ml). The solution was stirred for 1 h at room temperature. Cu(OAc)2·H2O (0.020 g, 0.01 mmol) was then added and the resulting solution was stirred for 3 h. All the volatiles were removed under vacuum and the residue was dissolved in a mixture of CH2Cl2 and DMF (v/v = 5:2). The resulting solution was allowed to stand at room temperature for about 7 d, after which rhombic crystals of (I) were collected for X-ray analysis.

Refinement top

H atoms bonded to C atoms were refined in idealized positions using the riding-model approximation, with C—H = 0.93 (Cp) and 0.96 Å (methyl), and with Uiso(H) = 1.2Ueq(C). Atoms C29, C30, C31, C32 and C33 of one Cp group were refined with the same anisotropic displacement parameters using the EADP instruction in SHELXL97 (Sheldrick, 1997). The same operation was also carried out on the methyl C atoms of the DMF molecules (C37, C38, C40 and C41).

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.
