Comment top

As part of our ongoing interest in the structure of iron complexes (Zhu et al., 2003), we report herein the crystal structure of the title compound, a new iron(II) complex, (I), Fig. 1, derived from the Schiff base ligand 2-(butyliminomethyl)-4-chlorophenol.

The FeII atom in (I) is four-coordinated by two O and two N atoms from two Schiff base ligands, forming a square-planar geometry. The dihedral angle between the two benzene rings is 8.2 (3) °. The coordinate bond distances and angles (Table 1) are comparable to the values observed in other similar iron(II) complexes (Chen & Wang, 2006; Chen et al., 2007; Ran et al., 2006; Ye et al., 2007).

Experimental top

5-Chlorosalicylaldehyde (31.2 mg, 0.2 mmol), butylamine (14.6 mg, 0.2 mmol), and FeCl2 (12.6 mg, 0.1 mmol) were dissolved in methanol (30 ml). The mixture was stirred for 30 min at room temperature in an atmosphere of argon. The resulting solution was left in air for a few days, yielding brown crystals.

Refinement top

H atoms were placed in idealized positions and constrained to ride on their parent atoms with C–H distances in the range 0.93–0.97 Å, and with Uiso(H) set at 1.2Ueq(C) and 1.5Ueq(methyl C).

Special details top

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.
