(Received 28 November 2011; accepted 12 December 2011; online 17 December 2011)

The Ni2+ ion in the title complex, [Ni(C3H5OS2)2(C6H4N2)2], is in a strongly distorted octa­hedral coordination environment formed by an N2S4 donor set, with the Ni2+ ion located on a centre of inversion. In the crystal, weak C—H⋯S and C—H⋯N inter­actions are observed.

Comment top

Xanthates (O-alkyl/aryl dithiocarbonates) have been known for a long time and many adducts of metal xanthates with different ligands have been prepared and studied in the last several decades. Adducts of transition metal xanthates with N-donor ligands are well represented in the literature, the most extensively studied being those of nickel(II). Nitrogen containing adducts of nickel(II) xanthates are known to adopt a variety of supramolecular assemblies (Tiekink & Haiduc, 2005). The Ni atom in (I) is located on a center of inversion and exists within a trans-N2S4 donor set that defines an approximately octahedral coordination geometry. The chelating xanthate ligand forms essentially equivalent Ni—S bond distances; this equivalence is reflected in the parameters defining the xanthate ligand. The bond angles around the Ni atom are in the range of 73.83 (2) to 180.00 (3)°. The Ni—S bond lengths, Ni1—S1 = 2.4335 (5); Ni1—S2 = 2.4450 (6) Å, are in good agreement with those reported for other Ni-dithiocarbonato complexes (Tiekink & Haiduc, 2005; Dakternieks et al., 2006; Hill & Tiekink, 2007; Hogarth et al., 2009). Molecules in the unit cell are packed together to form well defined layers. While no classical hydrogen bonds are present, the C—H···S and C—H···N hydrogen bonds (Table 1) play important role in stabilizing the crystal structure.

Experimental top

The title complex was prepared by stirring the parent nickel(II) ethylxanthate (0.781g,0.0026 mol.) with 3-cyanopyridine(0.541g, 0.0052 mol.) in acetone(60 ml) for one hour. Green crystals of (I) were isolated by the slow evaporation of the resulting solution of the complex.

Refinement top

All H atoms were positioned geometrically and were treated as riding on their parent C atoms, with C—H distances of 0.93–0.97 Å and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methylC).

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.
