In the ionic title complex, (C13H11N2)2[Ni(C4N2S2)2], the NiII ion is located on an inversion centre so the contains one-half [Ni(mnt)2]2− dianion (mnt2− is maleonitriledithiolate) and one 1-(3-cyanobenzyl)pyridinium cation ([CNBzPy]+). The NiII ion in the [Ni(mnt)2]2− anion is coordinated by four S atoms of two mnt2− ligands, and exhibits square-planar coordination geometry. In the [CNBzPy]+ cation, the benzene and pyridine rings are twisted with respect to the C/C/N plane incorporating the methylene C atom that links them. The is stabilized by Coulombic interactions.

Disodium maleonitriledithiolate (456 mg, 2.5 mmol) and nickel chloride hexahydrate (297 mg, 1.25 mmol) were mixed under stirring in water (20 mL) at room temperature. Subsequently, a solution of 1-(3-cyanobenzyl)pyridinium iodide (488 mg, 2.5 mmol) in methanol (10 mL) was added to the mixture, and the red precipitate that was immediately formed was filtered off, and washed with methanol. The crude product was recrystallized in acetone (20 mL) to give red block crystals. Anal. Calcd. for C34H22N8NiS4: C, 55.98; H, 3.04; N, 15.36%. Found: C, 56.00; H, 3.08; N, 15.33%.
The H atoms were placed to the bonded parent atoms in geometrically idealized positions (C—H = 0.93, or 0.97 Å) and refined as riding atoms, with Uiso(H) = 1.2Ueq(C).
Molecular solids based on transition metal dithiolene complexes have attracted intense interest in recent years, not only owing to the fundamental research of magnetic interactions and magneto-structural correlations but also to the development of new functional molecule-based materials (Robertson & Cronin, 2002), Much work has been performed in molecular solids based on M[dithiolene]2 complexes owing to their application as building blocks in molecular-based materials showing magnetic, superconducting, and optical properties (Nishijo et al., 2000; Ni et al., 2005). Herein we report the
of the title compound (I).The molecular structure of (I) is illustrated in Fig. 1.The
is formed by with one half anion and one cation.The Ni II ion is coordinated by four sulfur atoms of two mnt2- ligands, and exhibits square-planar coordination geometry. The is stabilized by coulombic interactions. The bond lengths and angles are in good agreement with related compounds [Ni(mnt)2]2- Table 1, (Ni et al., 2004; Ren et al., 2004).For background to the development of new functional molecule-based materials, see: Robertson & Cronin (2002).

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. |

Molecular solids based on transition metal dithiolene complexes have attracted intense interest in recent years, not only owing to the fundamental research of magnetic interactions and magneto-structural correlations but also to the development of new functional molecule-based materials (Robertson & Cronin, 2002), Much work has been performed in molecular solids based on M[dithiolene]2 complexes owing to their application as building blocks in molecular-based materials showing magnetic, superconducting, and optical properties (Nishijo et al., 2000; Ni et al., 2005). Herein we report the crystal structure of the title compound (I).
The molecular structure of (I) is illustrated in Fig. 1.The asymmetric unit is formed by with one half anion and one cation.The Ni II ion is coordinated by four sulfur atoms of two mnt2- ligands, and exhibits square-planar coordination geometry. The crystal structure is stabilized by coulombic interactions. The bond lengths and angles are in good agreement with related compounds [Ni(mnt)2]2- Table 1, (Ni et al., 2004; Ren et al., 2004).
