Comment top

Recently, we reported the synthes and crystal structure of iron (III) hetero-ligand complexes such as [Fe(bipy)Cl4][bipy.H], (II), [Fe(5,5'-dmbpy)2Cl2][FeCl4], (III), (Amani, Safari & Khavasi 2007), [Fe(phen)Cl3(CH3OH)].CH3OH, (IV), (Khavasi et al., 2007), [Fe(bipy)Cl3(DMSO)], (V) and [Fe(phen)Cl3(DMSO)], (VI), (Amani, Safari, khavasi & Mirzaei, 2007), [Fe(phen)Cl4][phen.H], (VII), (Khavasi et al., 2008), [Fe(4,4'-dmbpy)Cl4][4,4'-dmbpy.H], (VIII) and [Fe(4,4'-dmbpy)Cl3(DMSO)], (IX), (Amani et al., 2009) [where bipy is 2,2'-bipyridine, 5,5'-dmbpy is 5,5'-dimethyl-2,2'-bipyridine, phen is 1,10-phenanthroline, DMSO is dimethyl sulfoxide and 4,4'-dmbpy is 4,4'-dimethyl-2,2'-bipyridine].

There are several FeII complexes, with formula, [FeCl2(N—N)], such as [FeCl2(6,6'-dmbpy)], (X), (Chan & Baird 2004), [FeCl2(BDP)], (XI), (Handley et al., 2001) and [FeCl2(DEI)], (XII), (Gibson et al., 2002) [where 6,6'-dmbpy is 6, 6'-dimethyl-2, 2'-bipyridine, BDP is 1,3-bis(dimethylamino) propane and DEI is N,N'-dicyclohexyl-1,2-ethanedi-imine] have been synthesized and characterized by single-crystal X-ray diffraction methods. We report herein the synthesis and crystal structure of the title compound (I).

In the molecule of the title compound, (I), (Fig. 1), the FeII atom is four-coordinated in distorted tetrahedral configurations by two N atoms from one 2, 2'-biquinoline and two terminal Cl atoms. The Fe—Cl and Fe—N bond lengths and angles (Table 1) are within normal range (X). In this complex, Fe—N average distance is 2.1029 (15)Å and the Fe—Cl average bond distance is 2.2303 (6) Å. The Fe—N average bond distances in high-spin FeII and FeIII phenanthroline and bipyridine complexes are around 2.2 Å. However, low-spin FeII and FeIII complexes, the Fe—N distances less than 2 Å were reported (Figgis et al., 1983; Kulkarni et al., 1998). Therefore, in the molecule of the title compound, the Fe—N bond distance is unambiguously high-spin FeII. It seems substitution in the 6 position of bipyridine is crucial to stabilize FeII high-spin versus (FeII) especially low-spin. Also, biquinoline result in auto reduce of FeIII to FeII.

The π-π contacts between the pyridine rings, Cg2···Cg2i, Cg2···Cg4i, Cg3···Cg3ii, Cg3···Cg5i, Cg4···Cg4ii and Cg5···Cg3ii [symmetry cods: (i) 1-X, 1-Y, 1-Z, (ii) 1-X,-Y,1-Z, where Cg2, Cg3, Cg4 and Cg5 are centroids of the rings (N1/C1/C6—C9), (N2/C10—C13/C18), (C1—C6) and (C13—C18), respectively] further stabilize the structure, with centroid-centroid distance of 3.7611 (3), 3.7603 (4), 3.5292 (4), 3.5336 (5) and 3.6656 (4) Å, respectively. It seems this π-π stacking is effective in the stabilization of the crystal structure (Fig. 2).

Experimental top

A solution of 2,2'-biquinoline (0.20 g, 0.78 mmol) in methanol (6 ml) and chloroform (2 ml) was added to a solution of FeCl3.6H2O (0.07 g, 0.26 mmol) in methanol (6 ml) and chloroform (2 ml) and the resulting yellow solution was stirred for 15 min at room temperature. This solution was left to evaporate slowly at room temperature. After two weeks, red blocks of (I) were isolated (yield 0.07 g, 70.3%).

All H atoms were positioned geometrically (C—H = 0.93Å) and refined as riding with Uiso(H)=1.2Ueq.

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.
