(Received 21 November 2007; accepted 22 November 2007; online 6 December 2007)

The crystal structure of the title compound, [ZnCl2(C10H8N2S)], consists of a six-membered chelate ring in which the Zn atom is approximately tetra­hedrally coordinated by two chloride ions and by the two pyridyl N atoms of a single di-2-pyridyl sulfide ligand. As usual for this type of complex, the sulfide group does not participate in zinc coordination. The dihedral angle between the two pyridine rings is 50.4 (1)°.

Comment top

Recently, we are interested in the synthesis, structures and thermal properties of coordination polymers based on zinc(II) halides and N-donor ligands (Bhosekar et al., 2007). We have found for example that most of the ligand rich compounds can be transformed into ligand deficient compounds on heating. Starting from these findings we have initiated systematic investigations on this topic. In these investigations we have reacted zinc(II) chloride with 2,2'-bipyridyldisulfide. In this reaction, simultaneously a cleavage of the S—S bond takes place leading to the formation of di-2-pyridyl sulfide (dps). In further reaction with zinc(II) chloride the title compound (I) is formed. To identify this product in further reaction by X-ray powder diffraction, a structure determination was performed.

In general dps is a versatile ambidentate ligand that, due to its conformational flexibility, can act in N,N'-bidentate (Tresoldi et al., 1992; Kondo et al., 1995 and Nicolò et al., 1996) or bridging (Tresoldi et al., 1991 and Teles et al., 1999) coordination modes toward many metals, resulting in complexes with different stereochemistry. When dps is bonded to the metal as a chelate ligand, a six-membered ring in boat conformation is formed, differently from its rigid analogues 2,2'-bipyridine that generates a pentacyclic chelate in a planar arragement. In addition, in some cases dps can act as tridentate ligand in a N,N,S-coordination mode involving metal-sulfur interactions (Anderson & Steel, 1998).

In the crystal structure the coordination geometry about the Zn(II) ion is approximately tetrahedral with bonds being formed to two chloride ions and the two pyridyl nitrogen atoms of a single dps ligand (Fig. 1). These latter interactions result in the formation of a six-membered chelate ring, which is in a boat conformation. The angles at Zn(II) range from 93.85 to 115.66°, the largest being N—Zn—Cl. The Zn—Cl and Zn—N distances are in the range of 2.057 (2)–2.061 (2) and 2.2192 (8)–2.2261 (8) Å. The structural parameters in the dps molecule are quite regular. In particular the C—S bonds, 1.782 (3) and 1.780 (3) Å, are in good agreement with those expected for C(sp2)-S bonds (1.77 Å).

Experimental top

ZnCl2 and 2,2'-bipyridyldisulfide was obtained from Alfa Aesar and methanol was obtained from Fluka. 0.0313 mmol (4.3 mg) zinc(II) chloride, 0.125 mmol (27.5 mg) 2,2'-bipyridyldisulfide and 3 ml of methanol were transfered in test-tube, which were closed and heated to 110 °C for three days. On cooling colourless block-shaped single crystals of (I) are obtained.

Refinement top

All H atoms were located in difference map but were positioned with idealized geometry and were refined isotropic with Ueq(H) = 1.2Ueq(C) of the parent atom using a riding model with C—H = 0.97 Å.

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.
