In the title compound, (C5H6N)[Fe(NCS)4(C5H5N)2]·4C5H3N3·C5H5N, the FeIII ion is located on an inversion centre and is six-coordinated by four N atoms of the thio­cyanate ligands and two pyridine N atoms in a trans arrangement, forming a slightly distorted octa­hedral geometry. A half-occupied H atom attached to a pyridinium cation forms an N—H⋯N hydrogen bond with a centrosymmetrically-related pyridine unit. Four pyrazine-2-carbo­nitrile mol­ecules crystallize per complex anion. In the crystal, ππ stacking inter­actions are present [centroid–centroid distances = 3.6220 (9), 3.6930 (9), 3.5532 (9), 3.5803 (9) and 3.5458 (8) Å].

Comment top

Molecular assemblies comprising from cationic and anionic modules are of special interest for crystal engineering and molecular magnetism (Fritsky et al., 2004). Formation of such compounds often can be mediated by different types of intermolecular interactions, such as co-ordination and hydrogen bonds, ionic and van der Waals interactions (Fritsky et al., 1998; Kanderal et al., 2005). Such assemblies may possess interesting functional properties and, in particular, indicate spin crossover behavior. In this regard, FeII thiocyanate complexes with aromatic N-donor ligands attract much attention considering the possible metal ion spin state modulation by variation of a ligand (Gamez et al., 2009) accompanied by coordination polymer formation. Particularly, as one of the simplest bridging N-donor ligands to design coordination polymers, pyrazine (pz) is known for the construction of spin crossover Hofmann-like clathrates with general formula [FeIIMII(pz)(CN)4] (M = Ni, Pd or Pt) (Niel et al., 2001). A combination of pz and thiocyanate ligands leads to the formation of two-dimensional coordination polymer [Fe(NCS)2(pz)2] with an antiferromagnetic exchange between metal centres (Real et al., 1991). In this context, we attempted to synthesize FeII thiocyanate complex with pyrazine-2-carbonitrile (cnpz). However, the reaction of [FeII(NCS)2(py)4] (py = pyridine) and cnpz in an organic media in air led to oxidation of FeII and to the formation of the title compound.

The compound consists of one complex anion [Fe(NCS)4(py)2]-, one pyridinium cation, one pyridine and four pyrazine-2-carbonitrile molecules (Fig. 1). The FeIII ion is located on an inversion centre and is sixfold coordinated by four N atoms of four thiocyanate anions and two N atoms of two pyridine ligands in a trans arrangement, forming a slightly distorted octahedral coordination geometry. The thiocyanate ligands are bound through N atoms and are quasi-linear [S1—C1—N2 = 179.41 (14), S2—C9—N3 = 179.33 (15)°], while the Fe—NCS linkages are bent [Fe1—N2—C1 = 163.20 (12), Fe1—N3—C9 = 167.56 (12)°]. These structural features are typical for the complexes where the NCS group is N-bound (Petrusenko et al., 1997). The distances between FeIII ion and N atoms of the thiocyanate anions [Fe1—N2 = 2.0424 (13), Fe1—N3 = 2.0370 (13) Å] are considerably shorter than those between FeIII and N atoms of the pyridine ligands [Fe1—N1 = 2.1320 (12)Å], that could be related to the higher affinity of the metal ion to negatively charged thiocyanate comparing with the neutral organic ligand. The C—N and C—C bond lenths in the coordinated pyridine ligands are normal and close to the values observed in the related structures (Moroz et al., 2010; Penkova et al., 2010).

In the title compound there are four solvent molecules of pyrazine-2-carbonitrile per each FeIII ion that interact with one another through ππ stacking, with distances between the centroids of 3.5532 (9), 3.5803 (9) and 3.5458 (8) Å (Fig. 2). One of the uncoordinated pyridines is protonated and the N-bound H atom is disodered between two equally populated positions, forming N—H···N hydrogen bonds (Table 1). Coordinated and solvent pyridine molecules also interact with one another via ππ contacts, with distances between the centroids of 3.6220 (9) and 3.6930 (9) Å (Fig. 3).

Experimental top

Crystals of the title compound were obtained by adding pyrazine-2-carbonitrile (52.5 mg, 0.5 mmol) to tetrakis(pyridine)bis(isothiocyanato)iron(II), [Fe(NCS)2(py)4], (48.8 mg, 0.1 mmol) in acetone (5 ml). The solution was left to evaporate in air. In one day this yielded red crystals that were collected, washed with water and dried in air (yield: 21 mg, 20%).

Refinement top

H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.95 and N—H = 0.88 Å and with Uiso(H) = 1.2Ueq(C,N). N-bound H atom of the uncoordinated pyridine is half-occupied due to the requirement of symmetry.

Experimental. Hydrogen atoms were positioned geometrically and constrained to ride on their parent atoms, with C—H = 0.95 Å, N—H = 0.88 Å, and Uiso = 1.2 Ueq(parent atom). The highest peak is located 0.70 Å from atom C18 and the deepest hole is located 0.48 Å from atom Fe1.

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.
