Comment top

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. Compound (I) crystallizes in monoclinic system, with one half [Ni(mnt)2]2- dianion and one 1-(2,6-dichlorobenzyl)-3-methylpyrazine cation in an asymmetric unit. The anion [Ni(mnt)2]2- possesses an approximated planar geometry and most of the bond lengths and angles are in good agreement with the various [Ni(mnt)2]2- compounds (Ni et al., 2004; Ren et al., 2004).

Experimental top

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-(2,6-dichlorobenzyl)-3-methylpyrazine iodide (952 mg, 2.5 mmol) in methanol (10 mL) was added to the mixture. The black precipitate that was immediately formed was filtered off and washed with methanol. The crude product was recrystallized in acetone (20 mL) to give black block crystals. Anal. Calcd. for C32H22Cl4N8NiS4: C 48.73, H 2.81, N 14.21%. Found: C 48.69, H 2.78, N 14.09%.

Refinement top

The H atoms were placed in geometrically idealized positions (C—H = 0.93–0.97 Å) and refined as riding atoms, with Uiso(H) = 1.2Ueq(C).

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.
