Abstract top

In the title complex, [Cu(C2H2ClO2)2(C12H8N2)(H2O)], the CuII ion is five-coordinated by two N atoms [Cu-N = 2.005 (2) and 2.029 (2) Å] from the 1,10-phenanthroline ligand, two O atoms [Cu-O = 1.943 (2)-1.966 (2) Å] from two 2-chloroacetate ligands and one water molecule [Cu-O = 2.253 (2) Å] in a distorted square-pyramidal geometry. The crystal structure exhibits intermolecular O-H...O hydrogen bonds, short Cl...Cl contacts [3.334 (1) Å] and [pi]-[pi] interactions [centroid-centroid distance 3.621 (11) Å].

Comment top

2-Chloroacetic acid and its derivatives are often used in the synthesis of mononuclear monomeric (Sieroń, 2007; Czylkowska et al., 2004) and polymeric compounds (Chen et al., 1996; Overgaard et al., 2003). In our search for new topogical structures, we selected the copper(II) ion with 2-chloroacetic acid in the presence of 1,10-phenanthroline as a co-ligand, and obtained the title compound, (I).

In (I) (Fig. 1), Cu1 exhibits a five-coordinated square-pyramidal environment, formed by two O atoms from two carboxyl ligands (Cu1—O1 1.943 (2) Å, Cu1—O3 1.966 (2) Å), one water molecule (Cu1—O5 2.243 (5) Å) and two N atoms (Cu1—N1 2.029 (2) Å, Cu1—N2 2.005 (2) Å) from 1,10-phenanthroline ligand.

In the crystal structure, there exist short intermolecular Cl···Cl contacts (Table 1), π···π stacking interactions between the aromatic rings from neighbouring molecules (Table 1), and intermolecular O—H···O hydrogen bonds (Table 2), which link the molecules into centrosymmetric dimers.

Experimental top

The reaction was carried out by the solvothermal method. 2-Chloroacetic acid (0.188 g, 2 mmol) and cupric acetate (0.199 g, 1 mmol) and 1,10-phenanthroline (0.180 g, 1 mmol) were added to the airtight vessel with 20 ml water. The resulting green solution was filtered. The filtrate was placed for sevaral days yielding blue block-shaped crystals.

The yield is 81% and elemental analysis: calc. for C16H14Cl2CuN2O5: C 42.82, H 3.14, N 6.24; found: C 42.55, H 3.39, N 6.32. The elemental analyses were performed with PERKIN ELMER MODEL 2400 SERIES II.

Refinement top

All H atoms were found in Fourier difference map, but placed in idealized positions (C—H 0.93–0.97 Å, O—H 0.85 Å), with Uiso(H)=1.2Ueq of the parent atom.

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.
