In the centrosymmetric binuclear cation of the title compound, [Cu(C8H7O4)(H2O)(C5H5N)2]2(ClO4)2, the CuII atoms are bridged by a pair of two dehydro­acetate anions in a bis-/monodentate mode. The distorted octa­hedral N2O4 coordination sphere of the metal cation is completed by two pyridine N atoms and one O atom of a water mol­ecule. The complex cations and the perchlorate counter anions are arranged in layers parallel to (100). O—H⋯O hydrogen bonds between the coordinating water mol­ecules and the perchlorate anions constitute ribbons parallel to [10-1]. C—H⋯O hydrogen bonds are also observed.

Comment top

Dehydroacetic acid is used for the synthesis of heterocyclic compounds, some of them with therapeutic activities useful for treatment of human diseases (Das & Livingstone, 1976; Mohan et al., 1981; Maiti et al., 1988). Schiff bases, on the other hand, are widely applied in the synthesis transition metal coordination compounds (Tan & Kok-Peng Ang, 1988; El-Kubaisi & Ismail, 1994; Munde et al., 2010), showing catalytic activities particularly in the oxidation reactions carried out according to the cytochrome P450 model (Ourari et al., 2008, 2011, 2012). Thus, we attempted to synthesize Schiff base half-units in order to use them as starting materials to obtain unsymmetrical tetradentate Schiff base complexes according the Danilova method's (Danilova et al., 2003). Here we describe the formation of a new dinuclear complex, [Cu(C8H7O4)(H2O)(C5H5N)2]2(ClO4)2], (I), prepared from dehydroacetic acid, copper perchlorate and pyridine in methanolic solution.

The molecular structure of the complex binuclear and centrosymmetric cation of (I) is illustrated in Fig. 1. The connection mode of the copper cations exhibits dimers, i.e. two copper cations are bridged by two dehydroacetate anions in a bis-/monodentate fashion. The asymmetric unit of (I) contains only half of such a dimer. The distorted octahedral coordination sphere around the copper cation is completed by two pyridine ligands and one water molecule. The bond lengths range from 1.922 (3) to 2.325 (3) Å for the Cu—O distances with one more considerably longer bond for Cu—O4 of 2.737 (3) Å; the Cu—N bond lengths are 2.005 (3) and 2.006 (3) Å.

The crystal packing in (I) can be described by alterning layers of cations and tetrahedral perchlorate anions arranged parallel to (100) (Fig. 2). Intermolecular O—H···O hydrogen bonds (Table 2) between the coordinating water molecules and perchlorate anions constitute ribbons parallel to [101]; C—H···O hydrogen bonding interactions eventually links these constituents (Fig. 3).

Experimental top

0.168 g (1 mmol) dehydroacetic acid and 0.373 g (1 mmol) copper bis-perchlorate hexahydrate were dissolved in 20 ml of methanol. To this solution 0.108 g (1 mmol) of 1,2-phenylendiamine was added with an excess of pyridine. The mixture was held under stirring and argon atmosphere for two hours. After that time a precipitate appeared that was recovered by filtration. The solid was washed several times with methanol before it was dried under vacuum (yield 64%). From the resulting filtrate crystals were obtained by slow evaporation.

Refinement top

The H atoms were localized on Fourier maps but introduced in calculated positions and treated as riding on their parent C atom with C—H = 0.96 Å (methyl) or 0.93 Å (aromatic) and with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(methyl). H1W and H2W protons of the water molecule were located in a difference Fourier map and were refined isotropically with Uiso(H) = 1.5Ueq(O).

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.
