In the title compound, [Fe(C₄₈H₃₆N₄)(C₄H₆N₂)₂]ClO₄·1.5C₄H₈O, the iron(III) metal is coordinated in a distorted octahedral geometry by four pyrrole N atoms of the porphyrin ligand in the equatorial plane and two N atoms of 2-methylimidazole ligands in the axial sites. The complex has a highly ruffled porphyrin core with mean absolute core-atom displacements C_a, C_b, C_m and C_av of 0.25 (5), 0.17 (12), 0.432 (16) and 0.25 (13) Å, respectively. One of the four phenyl groups of the porphyrin is disordered over two sets of sites with refined occupancy ratio of 0.718 (7):0.282 (7). The mean Fe—N_p (N_p is a porphyrin N atom) bond length [1.975 (9) Å] indicates the low-spin state of the iron atom. The two 2-methylimidazole ligands are nearly perpendicular and form a dihedral angle of 86.93 (10)°. The dihedral angles between the 2-methylimidazole ligands and the closest Fe—N_p vector are 38.04 (9) and 35.00 (7)°. In the crystal, the complex cations interact with the perchlorate anions through N—H⋯O hydrogen bonds, forming chains running parallel to [110].

Keywords: crystal structure; 2-methylimidazole; meso-tetrakis(p-tolyl)porphyrinato; iron(III); highly ruffled porphyrin core; hydrogen bonding.

1. Chemical context

The structural characterization of metalloporphyrin complexes with steric nitrogen-donor ligands has been undertaken intensively in order to understand the control of structures, spin states, and other physical properties. Many structures of ferric porphyrins with general formula [Fe(Porph)(L)₂]⁺ (Porph is a porphyrinato ligand and L is an N-bonded neutral ligand) and with the central Fe^III atom in an octahedral coordination are known. The first ferric porphyrin crystal structure with two sterically hindered axial ligands is [Fe(OEP)(2-MeHIm)₂]ClO₄, which was reported by Geiger and co-workers (Geiger et al., 1984 ). Subsequently, some other analogues have been reported, [Fe(TPP)(2-MeHIm)₂]ClO₄ (Scheidt et al., 1987 ), [Fe(TMP)(1,2-Me₂Im)₂]ClO₄ (Munro et al., 1995 ), [Fe(OETPP)(2-MeHIm)₂]·(0.33SbF^6–, 0.67Cl⁻) (Ogura et al., 2001 ), [Fe(OMTPP)(2-MeHIm)₂]Cl·3CD₂Cl₂ (Yatsunyk et al., 2003 ), [Fe(OMTPP)(2-MeHIm)₂]Cl·2CDCl₃ (Yatsunyk et al., 2003), perp-[Fe(OEP)(2-MeHIm)₂]Cl (Hu et al., 2006 ) (OEP, octaethylporphirin; TPP, tetraphenylporphphyrin; TMP, tetramesitylporphyrin; OETPP, octaethyltetraphenylporphyrin; OMTPP, octamethyltetraphenylporphyrin; 2-MeHIm, 2-methylimidazole; 1,2-Me₂Im, 1,2-dimethylimidazole). Herein, we report the structural properties of the iron(III) porphyrin complex [Fe(TTP)(2-MeHIm)₂](ClO₄)·1.5THF where the metal is likewise octahedrally coordinated.

2. Structural commentary

In the title compound (Fig. 1), the counter-ion to the positively charged bis(2-methylimidazole)[meso-tetrakis(p-tolyl)porphyrinato]iron(III) is a negatively charged perchlorate ion. One of the four phenyl groups of the porphyrin is disordered over two sets of sites [0.718 (7):0.282 (7)] and the dihedral angles between the disordered phenyl planes and the 24-atom mean plane are 72.4 (4) and 63.36 (12)°. Additional quantitative information on the structure is given in Fig. 2, which displays the detailed displacements of each porphyrin core atom from the 24-atom mean plane (in units of 0.01 Å). The mean values of the chemically unique bond lengths (in Å) and angles (in degrees), the orientations of the two 2-methylimidazole ligands including the values of the dihedral angles are also shown; the circle represents the position of the methyl group on the axial ligand. As indicated in Fig. 2, the 2-methylimidazole ligand containing the N7 atom makes a dihedral angle of 38.04 (9)°, the other making an angle of 35.00 (7)°, to the closest Fe—N_p vector. The relative orientation of the two 2-methylimidazole planes is nearly perpendicular, the dihedral angle being 86.93 (10)°. Fig. 2 also shows that the title complex has a highly ruffled porphyrin core conformation. The mean absolute core atom displacements of C_a, C_b, C_m, and C_av are 0.25 (5), 0.17 (12), 0.432 (16) and 0.25 (13) Å, respectively. The mean Fe—N_p (N_p is a porphyrin N atom) bond length is 1.975 (9) Å, similar to 1.974 (4) Å in (perp-[Fe(OEP)(2-MeHIm)₂]Cl) (Hu et al., 2006) and 1.970 (4) Å in [Fe(TPP)(2-MeHIm)₂]ClO₄ (Scheidt et al., 1987). These values are slightly shorter than 1.990 Å, which is typically observed for a low-spin iron(III) porphyrin complex (Scheidt & Reed, 1981 ).

Figure 2
Diagram of the porphyrinato core of the title compound. Mean values of the chemically unique bond lengths (in Å) and angles (in °) are shown. The numbers in parentheses are the s.u. calculated on the assumption that the averaged values are all drawn from the same population. The perpendicular displacements (in units of 0.01 Å) of the porphyrin core atoms from the 24-atom mean plane are also displayed. Positive values indicate a displacement toward the N7 2-methylimidazole nitrogen atom. The solid line in this perspective indicates the 2-methylimidazole ligand containing atom N7, and the dashed line indicates the 2-methylimidazole ligand containing atom N5. The small circle represents the position of the methyl group on the axial ligand.

The dihedral angles between the mean planes of the phenyl rings and the 24-atom mean plane are 59.55 (6), 82.53 (7), 72.4 (4) [and/or 63.36 (12)] and 75.17 (5)°, smaller than the same angles of 89.7, 83.3, 87.2 and 87.9° in [Fe(TMP)(1,2-Me₂Im)₂]ClO₄ (Munro et al., 1995). The reason for the difference could be the steric effect of the mesityl groups of [Fe(TMP)(1,2-Me₂Im)₂]ClO₄, which hinders the rotation of the benzene groups.

3. Supramolecular features

N—H⋯O hydrogen bonds are observed in the crystal structure of the title compound (Table 1). As shown in Fig. 3, the perchlorate ion bridges two adjacent porphyrin molecules through hydrogen bonding with imidazole ligands, which can be formulated as N8—H8A⋯O2—ClO₂—O3⋯H6A—N6, forming a chain parallel to [110]. The hydrogen-bonding distances, 2.942 (3) (O3⋯N6) and 2.949 (3) Å (O2⋯N8), are consistent with the reported values 2.92 or 3.08 Å (Scheidt et al., 1987; Hu et al., 2006), and fall in the range 2.70–3.30 Å reported for intermolecular N⋯O interactions (Bertolasi et al., 1995 ). It is noteworthy that one of the tetrahydrofuran molecules, which is disordered about an inversion center, occupies the channels between the [Fe(TTP)(2-MeHIm)₂]ClO₄ complex molecules (Fig. 4).

4. Synthesis and crystallization

General Procedure: All reactions were carried out using standard Schlenk techniques under argon unless otherwise noted. Tetrahydrofuran (THF) and hexanes were distilled from sodium and benzophenone ketyl. H₂(TTP) and [Fe(TTP)Cl] were prepared according to the reported methods (Adler et al., 1970 ; Fleischer et al., 1971 ).

4.1. Synthesis of [meso-tetrakis(p-tolyl)porphyrinato]iron(III) perchlorate

[Fe(TTP)Cl] (500 mg, 0.652 mmol) and AgClO₄ (136 mg, 0.657 mmol) were dissolved in 50 mL THF. After 12 h reaction, the solution was filtered and then evaporated to dryness under vacuum. The resulting purple solid, [Fe(TTP)ClO₄], was harvested that was dried in vacuo (531.54 mg; yield 100%). UV–vis (CH₂Cl₂): 411.89, 516.5 nm.

4.2. Synthesis of bis(2-methyl-1H-imidazole-κN³)(meso-tetra-p-tolylporphyrinato-κ⁴N)iron(III) perchlorate tetrahydrofuran sesquisolvate

[Fe(TTP)ClO₄] (20 mg, 0.024 mmol) and excess 2-methylimidazole (0.164 g, 2 mmol) were dissolved in 7 mL THF. After 10 min, the solution was transferred into glass tubes which were layered with hexanes as nonsolvent. Dark-purple block-shaped crystals suitable for a single-crystal X-ray diffraction study were collected after 15 d. UV–vis (CH₂Cl₂): 415.44, 509.68, 571.87, 612.00 nm.

5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. The hydrogen atoms of the two imidazole nitrogen atoms of the axial ligands were located in a difference Fourier map and refined freely. All other hydrogen atoms were placed in calculated positions, with C—H = 0.95 or 0.98 Å for aryl or methyl H atoms, respectively, and refined using a riding model with U_iso(H) = 1.5U_eq(C) for methyl H atoms or U_iso(H) = 1.2U_eq(C, N) otherwise. One THF molecule is disordered over two sets of sites about an inversion center with an occupancy factor of 0.5. During the refinement, the O—C, C—C and C⋯C distances within the disordered THF molecule were constrained to be 1.42 (1), 1.50 (1) and 2.40 (1) Å, respectively. One of the four phenyl groups was found to be disordered over two orientations and the site occupancy factors (SOFs) of disordered moieties are refined by means of a `free variable'. The refined final SOFs were 0.718 (7) and 0.282 (7). Two carbon atoms (C39 and C43) of the tetrahydrofuran molecules and one carbon atom (C12) of a methyl group exhibited unusually large displacement parameters and thus were refined using SIMU and ISOR restraints. Seven outliers were omitted in the last cycles of refinement.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
