1,10-Phenanthroline-5,6-dione was prepared according to the literature method (Yamada et al., 1992). The complex was prepared by mixing a 10 ml me thanolic solution of copper(II) chloride dihydrate (171 mg, 0.5 mmol) and 1,10-phenanthroline-5,6-dione (105 mg, 0.5 mmol) in methanolic solution (10 ml) was added, and then the solution was stirred for about 3 h at room temperature. The green precipitate was collected by filtration. Crystals of suitable quality for X-ray analysis were obtained by slow evaporation of a dimethyl sulfoxide solution.
All H atoms were initially located in a difference Fourier map, but refined using a riding model with with C—H distances in the range 0.95–1.00 Å, O—H = 0.91 and 0.97Å and Uiso(H) = 1.2Ueq(C,O). The methyl H atoms were then constrained to an ideal geometry, with C—H distances of 0.98 Å and Uiso(H) = 1.5Ueq(C), but each group was allowed to rotate freely about its C—C bond.
The complexes of 1,10-phenanthroline-5,6-dione (phendione) could intercalate within the base pairs of DNA (Ghosh et al., 2006; Coyle et al., 2003). Based on this finding, the derivatives of phendione are promising in the treatment of many diseases (Deegan et al., 2006; Eshwika et al., 2004), cancer amongst all, and their development is still in progress. Following our interest in biological activity of metal complexes, we decided to focus our attention on the complexes of phendione (Xu et al., 2006).
The asymmetric unit of complex consists of a monomeric copper(II) complex, one dimethyl sulfoxide (DMSO) molecule and one water molecule. The copper(II) ion is in a five-coordinated environment. The phendione acts as bidentate ligand [Cu—N1 = 2.062 (3)Å and Cu—N2 = 2.059 (3) Å], forming with the metal ion a five-membered chelate ring with a bite angle of 80.38 (12)°. A monodentate dimethyl sulfoxide interacts with copper at a distance [Cu—O3 = 2.019 (3) Å]. Addison et al. (1984) have proposed a structural index for five-coordinated geometries of copper(II). This index has been defined as τ = (β-α)/60, with β and α being the two largest angles. For perfect tetragonal geometry τ equals zero, while it becomes unity for perfect trigonal bipyramidal geometry. From the bond lengths and angles it can be concluded that the coordination geometry around copper(II) is clearly square-pyramidal (τ = 0.14) with a CuN2OCl plane and one chloride ion in the apex. The copper(II) ion is shifted 0.3319 Å out of the plane defined by (N1, N2, O3 and Cl1) and directed towards Cl2.
The water molecule connects the complex and a dimethyl sulfoxide solvent molecule by O—H···O and O—H···Cl hydrogen bonds.

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. |

The complexes of 1,10-phenanthroline-5,6-dione (phendione) could intercalate within the base pairs of DNA (Ghosh et al., 2006; Coyle et al., 2003). Based on this finding, the derivatives of phendione are promising in the treatment of many diseases (Deegan et al., 2006; Eshwika et al., 2004), cancer amongst all, and their development is still in progress. Following our interest in biological activity of metal complexes, we decided to focus our attention on the complexes of phendione (Xu et al., 2006).
The asymmetric unit of complex consists of a monomeric copper(II) complex, one dimethyl sulfoxide (DMSO) molecule and one water molecule. The copper(II) ion is in a five-coordinated environment. The phendione acts as bidentate ligand [Cu—N1 = 2.062 (3)Å and Cu—N2 = 2.059 (3) Å], forming with the metal ion a five-membered chelate ring with a bite angle of 80.38 (12)°. A monodentate dimethyl sulfoxide interacts with copper at a distance [Cu—O3 = 2.019 (3) Å]. Addison et al. (1984) have proposed a structural index for five-coordinated geometries of copper(II). This index has been defined as τ = (β-α)/60, with β and α being the two largest angles. For perfect tetragonal geometry τ equals zero, while it becomes unity for perfect trigonal bipyramidal geometry. From the bond lengths and angles it can be concluded that the coordination geometry around copper(II) is clearly square-pyramidal (τ = 0.14) with a CuN2OCl plane and one chloride ion in the apex. The copper(II) ion is shifted 0.3319 Å out of the plane defined by (N1, N2, O3 and Cl1) and directed towards Cl2.
The water molecule connects the complex and a dimethyl sulfoxide solvent molecule by O—H···O and O—H···Cl hydrogen bonds.
