Aquatris(1H-benzimidazole-[kappa]N3)(dichloroacetato-[kappa]O)copper(II) dichloroacetate dihydrate

Y.-F. Li and F.-F. Jian

Abstract top

The title compound, [Cu(C2HCl2O2)(C7H6N2)3(H2O)]C2HCl2O2·2H2O, was prepared by reaction of copper(II) 2,2-dichloroacetic acid and benzimidazole in ethanol solution. The compound shows a regular trigonal-bipyramidal stereochemistry. The CuII centre possesses a five-coordinated environment, coordinated by three N atoms from the three benzimidazole ligands and two O atoms, one from the dichloroacetate ligand and the other from the coordinated water molecule. The molecular structure and packing are stabilized by O-H...O and N-H...O hydrogen bonds. The Cl atoms are disordered over two sites, with relative occupancies 0.67 (3) and 0.33 (3).

Comment top

The penta-coordinated copper complexes have been attracting great interest for their diverse stereo and physicochemical properties (Tyagi et al., 1984). Therefore the coordination chemistry of Cu(II) with ligands is of great interest. In this paper, we reported the synthesis and crystal structure of the title compound.

In the crystal structure of the title compound (Fig. 1), all the bond length and angle are in the normal range. (Barszcz et al., 2004). The title compound consists of discrete monovalent complex cations, dichloroacetic acid anion and solvent water molecules. The dichloroacetic ions appear to be loosely held in lattice holes by Coulombic forces and by weak hydrogen bonds to the solvent water molecules. The interionic hydrogen bonds play an important role in the crystal packing and the stability of the complex. The Cl1 and Cl2 atoms are disordered.

Experimental top

Solid copper(II) 2,2-dicholoracetate, C4H2Cl4Cu1O4 0.32 g (1 mmol) and benzimidazole 0.35 g (3 mmol) were added in 50 ml anhydrous alcohol under stirring. The mixture was refluxed for 5 h. The blue solution was filtered and the filtrate was left to stand undisturbed. Upon slow evaporation at room temperature, a blue crystalline solid appeared three days later and was separated by filtration. Determined by X-ray crystallography.

Refinement top

H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H distances of 0.93–0.96 Å, and with Uiso(H) = 1.2Ueq of the parent atoms. The Cl1 atom and Cl2 atom are disordered over two sites, with relative occupancies 0.672 (34) and 0.328 (34).

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.
