The 12H11ClN)2[Ni(C2N2S3)2], comprises one cation and a half of Ni(tdas)2 (tdas = 1,2,5-thiadiazole-3,4-dithiolate) anion. The NiII atom is located at a centre of inversion. The NiII atom has a square-planar coordination with Ni—S distances of 2.2052 (4) and 2.1970 (5) Å. In crystal, weak C—H⋯S and C—H⋯Ni contacts are observed between the anions and cations.

The title complex was prepared by the direct reaction of 1:2:2 mol equiv. of NiCl2.6H2O, Na2tdas and 1-(4'-chlorobenzyl)pyridinium bromide in methanol. A brown product was given and purified through recrystallisation from the mixed solvent of methanol and water (yield 81%). The brown block single crystals suitable for X-ray analysis were obtained by slow evaporation of methanol solution of (I) at room temperature about 2 weeks.
All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.93 Å, Uiso=1.2Ueq (C) for aromatic and 0.97 Å, Uiso = 1.2Ueq (C) for CH2 atoms.

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. |

Much effort has been devoted to the study of bis(1,2-ditholene) transition metal complexes because of their extensive applications in molecular materials showing magnetic, superconducting, and optical properties. Among these complexes, [M(tdas)2]n- (tdas is 1,2,5-thiadiazole-3,4-dithiolate, n is 1 or 2) complexes show interesting magnetic properties with unusual phase transition and electro-conductive properties in the solid state. As a continuation of our work in this field, we have obtained a new ion-pair complex, [4ClBzPy]2[Ni(tdas)2] (I), by introducing 1-(4'-chlorobenzyl)pyridinium as a counterion into the system containing the [Ni(tdas)2]2- anion.
There are one [4ClBzPy]+ and a half of [Ni(tdas)2]2- anion in an asymmetric unit of (I). The nickel(II) ion of Ni(tdas)2 anion is situated at a center of symmetry of a square planar complex (Fig. 1). The two [4ClBzPy]+ ions are related to each other by the symmetry centre. The Ni1—S1 and Ni1—S2 bond distances are 2.205 (1)Å and 2.197 (1) Å (Table 1), and the S1—Ni1—S2 bond angle within the five-membered ring is 93.42 (2)°, as that have been found for other [Ni(tdas)2]2- structures. The dihedral angles between the C8—C9—N3 reference plane and these aromatic rings are 87.2 (2)° for a phenyl ring and 5.4 (2)° for a pyridine ring, respectively. The dihedral angle between the phenyl ring and the pyridine ring is 92.1 (2)°. The anions and the cations are involved in C4—H4···S2, C11—H11···S2 and C9—H9···Ni weak contacts (Fig. 2, Table 2). The distances of C9···Ni and H···Ni are 3.819Å and 2.895 (2) Å, respectively, while the bond angle is 159.36 (2)° (Brookhart et al., 2007).
