Abstract top

In the title compound, [Fe(C12H10N2O)3](ClO4)2, the metal center is coordinated by six N atoms from the three bidentate chelating ligands in a distorted octahedral coordination geometry, with overall formation of the meridional (OC-6-21) isomer. Intermolecular O-H...O hydrogen bonds between the hydroxyl groups of the cation and the counter-anions form an infinite one-dimensional chain in the c-axis direction.

Comment top

A large number of Schiff bases and their complexes have been studied for their interesting and important properties, such as their ability to reversibly bind oxygen, their catalytic activity in the hydrogenation of olefins and their photochromic properties (Osman, 2006). The synthesis of new Schiff bases and their metal complexes are the subject of ongoing research (Golcu et al., 2005; Lacroxin et al., 2004; Dhar et al., 2005). Similar to the ligands 2,2'-bipyridine and 1,10-phenanthroline, Schiff bases derived from 2-pyridinecarboxaldehyde provide the π-acidic α,α'-diimine fragment for metal coordination.

Very little effort has been spent in the preparation of Fe(II) Schiff base complexes (Thankarajan & Mohanan, 1986; Sharma & Dubey, 1994), despite their importance as complexes containing a metal in a low and potentially unstable oxidation state, as well as involving relatively unstable ligands, the Schiff bases (Shaker et al., 2003). Such ligands are hydrolytically unstable but the metal ions stabilize the aldimine linkage to hydrolytic splitting (Dash et al., 1983).

In this context, the title complex of Fe(II) with 2-pyridinecarboxaldehyde(p-hydroxyphenylimine) has been prepared and its crystal structure is reported here. The central Fe atom is coordinated by three ligand molecules through the nitrogen atoms in a bidentate manner. The coordination geometry is distorted octahedral. The complex crystallizes as the meridional isomer in the monoclinic centrosymmetric space group P21/c. The meridional isomer is associated with two different orientations of the bidentate ligands in a 2:1 distribution. These two different types of geometry are reflected in different dihedral angles between the aromatic and heteroaromatic rings. For the ligands which have the same orientation (N1···N2 and N3···N4 bidentate ligands) the dihedral angles are similar, viz. 36.72 (16) and 34.21 (16)°, respectively, whereas for the bidentate ligand N5···N6 with different orientation the angle is 50.30 (17)°. The Fe(II)—N(pyridine) distances are shorter than the Fe(II)—N(imine) bonds (see Table 1). Classical intermolecular O—H···O hydrogen bonds between the OH groups of the cation and the anions form an infinite one-dimensional chain in the c direction.

Experimental top

Attempts to synthesize Fe(II) complexes with the Schiff base ligand 2-pyridinecarboxaldehyde(p-hydroxyphenylimine) in a molar ratio M:L 1:1 or 1:2 resulted in the same crystalline complex [Fe(C12H10N2O)3](ClO4)2, independent of reactant stoichiometry. The ligand 2-pyridinecarboxaldehyde(p-hydroxyphenylimine) was prepared following the procedure developed in the literature (Cloete & Mapolie, 2006). Stoichiometric amounts of Fe(ClO4)2.xH2O (0.255 g, 1 mmol) and 2-pyridinecarboxaldehyde(p-hydroxyphenylimine) (0.198 g, 1 mmol respectively 0.296 g, 2 mmol) were dissolved in acetonitrile (40 ml) and stirred under reflux to promote the complete formation of the purple complex, [Fe(C12H10N2O)3](ClO4)2. Single crystals suitable for X-ray diffraction were obtained by slow diffusion of diisopropyl ether into an acetonitrile solution of the complex at room temperature.

Refinement top

H atoms were placed in calculated positions and refined using a riding model with C—H distances of 0.93 Å, O—H distances of 0.82 Å, Uiso(H) = 1.2Ueq(C), Uiso(H) = 1.5Ueq(O).

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.
