Cu(II)–[1,8-bis(pyridin-2-yl)-3,6-dithiaoctane] complex has demonstrated biological activity against human tumor cervix line HeLa, which can be related to bio-mimetic Cu-SOD activity. Electrochemical studies indicate that the high flexibility of the 1,8-bis(pyridin-2-yl)-3,6-dithiaoctane ligand towards the preferential geometry of central atom could be an important factor in biological activity. However, the crystal structure of this compound was not obtained (Rodríguez-Torres et al., 2009).

The asymmetric unit of the title compound contains one complex cation [Cu(pdto)(H₂O)]²⁺ [pdto = 1,8-bis(pyridin-2-yl)-3,6-dithiaoctane], two nitrate anions and one acetonitrile solvent molecule (Fig. 1). The complex cation consists of a five-coordinated Cu^II ion in a distorted squared-pyramidal environment. The basal sites are occupied by N1, N2, S1 and S2 of the 1,8-bis(pyridin-2-yl)-3,6-dithiaoctane ligand (Humphery et al., 1988). The basal Cu—N/S bond lengths are in a range of 2.0169 (17)–2.3488 (6) Å. The aqua ligand in the apical position has a Cu1—O1W bond distance of 2.1342 (16) Å, 0.129 Å shorter than that of 2.263 Å observed in [Cu(pdto)(ClO₄)]ClO₄ (Brubaker et al., 1979). The basal CuN₂S₂ plane presents a slight distortion from planarity (τ = 0.1621) (Addison et al., 1984), as shown by the displacements of the atoms from a mean plane through them; the metal ion is situated 0.2260 (5) Å above the N1/N2/S1/S2 plane [least-squares plane: 7.663 (2)x + 1.291 (4)y + 9.420 (4)z = 14.302 (4)].

The nitrate anions and acetonitrile molecule are not involved in the coordination sphere of the Cu ion. In the crystal, O—H···O and weak C—H···O hydrogen bonds stabilize the crystal packing (Table 1). The water molecule (O1W) interacts with O1 and O5 acceptor atoms of the nitrate anions, forming a C₂²(5) motif.

Experimental top

Cu(NO₃).2.5H₂O (0.129 g, 0.56 mmol) was dissolved in 20 ml of anhydrous acetonitrile, followed by slow addition of 1,8-bis(pyridin-2-yl)-3,6-dithiaoctane (0.1693 g, 0.56 mmol) contained in 5 ml of anhydrous acetonitrile. A deep blue solution was obtained, and by slow ether diffusion, crystals suitable for X-ray analysis were obtained after 3 days.

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.
