(Received 22 November 2008; accepted 7 December 2008; online 10 December 2008)

In the title compound, [Fe(C₂₀H₁₄N₄O₂)Cl], the Fe^III ion is in a distorted square-pyramidal environment, with two pyridine and two deprotonated amide N atoms in the basal plane and the Cl ion in the apical position. The Fe^III ion is displaced from the basal plane of the square- pyramid towards the apical Cl atom by 0.2942 (4) Å. The molecules are linked into a three-dimensional network by C—H⋯Cl and C—H⋯O hydrogen bonds.

Comment top

The chemistry of macrocyclic complexes has attracted the interest of both inorganic and bioinorganic chemists in recent years. Iron(III) complexes are involved in numerous biological redox reactions performed by metalloenzymes (Momenteau et al., 1994). As part of our studies on catalysis by N4 non-porphyrin complexes (Liu et al., 2006; Yang et al., 2007), we report here the crystal structure of a iron(III) complex with 1,2-[bis(6'-pyridine-2'-carboxamido)-ethane]benzene.

As shown in Fig.1, the complex has a five-coordinate structure with two pyridine and two deprotonated amide N atoms in the basal plane while the Cl ion is bonded to the Fe^III center in the apical position. The geometry around the Fe^III ion is approximately square-pyramidal. The Fe—N(amide) distances are shorter than the Fe—N(pyridine) distances (Table 1), both of which are shorter than the Fe—N distances found in the non-ring related Fe—N4 complexes such as [NEt₄][Fe(bbpc)Cl₂][H₂bbpc is N,N'-(4,5-dichloro-o-phenylene)bis(4-tertbutylpyridine-2-carboxamide)] (Xu et al., 2007). The Fe—Cl distance of 2.3080 (8) Å is slightly shorter than that observed in [Fe(bbpc)Cl₂](Et₄N) (2.3299 (9) Å and 2.3880 (9) Å), while it is longer than that in [FeCl(meso-NH₂-octaethylporphyrin)] (2.2596 (8) Å, Sankar et al., 2004).

In the crystalline state, the molecules are linked into a three-dimensional network by C—H···Cl and C—H···O hydrogen bonds (Table 2).

Experimental top

1,2-[Bis(6'-pyridine-2'carboxamido)-ethane]benzene (132 mg, 0.38 mmol) and sodium acetate (80 mg, 0.76 mmol) were added to a stirred solution of FeCl₃.6H₂O (244 mg, 0.9 mmol) in CH₃OH (20 ml). The colour of the mixture turned green almost immediately. The mixture was refluxed for 3 h and dark green microcrystals appeared. They were collected by filtration, washed with methanol, and air-dried. (123 mg, yield 75%). Single crystals suitable for X-ray diffraction were grown via diffusion of Et₂O into a DMF solution of the complex. Selected IR data (KBr, cm^-1):ν=1629 (C=O), 1602 (C—N), 1572, 1346, 1287, 1142, 1083, 1081, 762. MS (FAB): 398.3([Fe(bpeb)]⁺).

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 F^2^ against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F^2^, conventional R-factors R are based on F, with F set to zero for negative F^2^. The threshold expression of F^2^ > σ(F^2^) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F^2^ are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
