The title compound, (C12H10BrFN)[Ni(C3S5)2], is an ion-pair complex consisting of N-(2-fluoro-4-bromobenzyl)pyridinium cations and [Ni(dmit)2]− anions (dmit = 2-thioxo-1,3-dithiole-4,5-dithiolate). In the anion, the NiIII ion exhibits a square-planar coordination involving four S atoms from two dmit ligands. In the weak S⋯S [3.474 (3), 3.478 (3) and 3.547 (3) Å] and S⋯π [S⋯centroid distances = 3.360 (3), 3.378 (2), 3.537 (2) and 3.681 (3) Å] interactions and C—H⋯F hydrogen bonds lead to a three-dimensional supramolecular network.

4,5-Bis(thiobenzoyl)-1,3-dithiole-2-thione (812 mg, 2.0 mmol) (Wang et al., 1998) was suspended in dry methanol (20 ml) and sodium (92 mg, 4.0 mmol) was added under a nitrogen atmosphere at room temperature to give a bright-red solution. NiCl2.6H2O (238 mg, 1 mmol) was then added, followed successively by addition of I2 (127 mg, 0.5 mmol) and a solution of N-(2-fluoro-4-bromobenzyl)pyridinium bromide (346 mg, 1 mmol) in methanol at an interval of approximately 20 min. The solution was stirred for a further 30 min and the resulting solid was collected by filtration. Single crystals of the title compound were obtained by evaporation of a dilute acetone solution over 1–2 weeks at room temperature.
H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93(aromatic) and 0.97(CH2) Å and Uiso(H) = 1.2Ueq(C).
Extensive research has been focused on the synthesis and characterization of bis(dithiolate)–metal complexes and their analogues, due to their properties and potential applications as conducting, magnetic and non-linear optical (NLO) materials (Cassoux, 1999). 2-Thioxo-1,3-dithiole-4,5-dithiolate (dmit) metal complex also is excellent building block employed for the construction of molecular magnetic materials (Li et al., 2006; Zang et al., 2006, 2009) apart from its well known
as molecular conductors (Akutagawa & Nakamura, 2000). We report herein the synthesis and of the title compound, a new ion-pair complex.The title compound comprises [NiIII(dmit)2]- anions and N-(2-fluoro-4-bromobenzyl)pyridinium cations (Fig. 1). The NiIII ion adopts a square-planar geometry coordinated by four S atoms from two dmit ligands, with Ni—S bond lengths ranging from 2.150 (2) to 2.169 (3) Å (Table 1). The [NiIII(dmit)2]- anions are in a parallel arrangement, with S···S interactions ranging from 3.474 (3) to 3.547 (3) Å. Two neighbouring anions are parallel in a head-to-tail inversion arrangement so that lone-pair (lp)···π (Egli & Sarkhel, 2007) interactions form between one terminal S atom of the anion and the other terminal π system of adjacent anion [S1···Cg1i = 3.378 (2) and S10i···Cg2 = 3.537 (2) Å. Cg1 and Cg2 are the centroids of C4–C6, S8, S9 ring and C1–C3, S2, S3 ring, respectively. Symmetry code: (i) x, -1+y, 1+z]. The anion and the neighbouring cation are also associated together through lp···π interactions between two terminal S atoms of the anion and the pyridine rings of two different cations [S1···Cg3ii = 3.360 (3) and S10···Cg3iii = 3.681 (3) Å. Cg3 is the centroid of C14–C18, N1 ring. Symmetry codes: (ii) 1+x, -1+y, z; (iii) x, 1+y, -1+z]. The weak S···S and S(lp)···π interactions lead to a three-dimensional supramolecular structure. In addition, the cations adopt a parallel arrangement, and the shortest distance between H14 from the pyridine ring of a cation and F1 atom from the neighbouring cation is 2.60 Å, indicating the existence of a C—H···F hydrogen bond (Table 2), which stabilizes the three-dimensional structure (Fig. 2).

Extensive research has been focused on the synthesis and characterization of bis(dithiolate)–metal complexes and their analogues, due to their properties and potential applications as conducting, magnetic and non-linear optical (NLO) materials (Cassoux, 1999). 2-Thioxo-1,3-dithiole-4,5-dithiolate (dmit) metal complex also is excellent building block employed for the construction of molecular magnetic materials (Li et al., 2006; Zang et al., 2006, 2009) apart from its well known electric conductivity as molecular conductors (Akutagawa & Nakamura, 2000). We report herein the synthesis and crystal structure of the title compound, a new ion-pair complex.
The title compound comprises [NiIII(dmit)2]- anions and N-(2-fluoro-4-bromobenzyl)pyridinium cations (Fig. 1). The NiIII ion adopts a square-planar geometry coordinated by four S atoms from two dmit ligands, with Ni—S bond lengths ranging from 2.150 (2) to 2.169 (3) Å (Table 1). The [NiIII(dmit)2]- anions are in a parallel arrangement, with S···S interactions ranging from 3.474 (3) to 3.547 (3) Å. Two neighbouring anions are parallel in a head-to-tail inversion arrangement so that lone-pair (lp)···π (Egli & Sarkhel, 2007) interactions form between one terminal S atom of the anion and the other terminal π system of adjacent anion [S1···Cg1i = 3.378 (2) and S10i···Cg2 = 3.537 (2) Å. Cg1 and Cg2 are the centroids of C4–C6, S8, S9 ring and C1–C3, S2, S3 ring, respectively. Symmetry code: (i) x, -1+y, 1+z]. The anion and the neighbouring cation are also associated together through lp···π interactions between two terminal S atoms of the anion and the pyridine rings of two different cations [S1···Cg3ii = 3.360 (3) and S10···Cg3iii = 3.681 (3) Å. Cg3 is the centroid of C14–C18, N1 ring. Symmetry codes: (ii) 1+x, -1+y, z; (iii) x, 1+y, -1+z]. The weak S···S and S(lp)···π interactions lead to a three-dimensional supramolecular structure. In addition, the cations adopt a parallel arrangement, and the shortest distance between H14 from the pyridine ring of a cation and F1 atom from the neighbouring cation is 2.60 Å, indicating the existence of a C—H···F hydrogen bond (Table 2), which stabilizes the three-dimensional structure (Fig. 2).
