Dichlorido(5,10,15,20-tetraphenylporphyrinato-κ⁴N)antimony(V) hexachloridoantimonate(V)

R. Soury, M. S. Belkhiria, M. Giorgi and H. Nasri

The asymmetric unit of the title compound, [Sb(C₄₄H₂₈N₄)Cl₂][SbCl₆], consists of one half of an antimony(V) tetraphenylporphyrin complex cation and one half of an hexachloridoantimonate(V) anion. In the complex cation, the Sb^V atom lies on an inversion center and is octahedrally coordinated by four N atoms from a macrocyclic tetraphenylporphyrinate ligand and two chloride ions. The complex cation has approximately a planar core with a maximum deviation of 0.018 (5) Å from the porphyrin mean plane. The average Sb—N distance is 2.062 (11) Å, while the Sb—Cl distance is 2.355 (1) Å. The Sb^V atom of the anion is also located on an inversion center. The [SbCl₆]⁻ octahedron exhibits rhombic distortion characterized by the Sb—Cl bond lengths [2.311 (3), 2.374 (2) and 2.393 (4) Å]. In the crystal, the cations and anions are linked C—H

Cl hydrogen bonds, forming a layer parallel to (211).

As part of our continuing studies of antimony porphyrin complexes (Soury et al., 2012), we report here the synthesis and crystal structure of the tiltle compound [Sb(tpp)Cl₂][SbCl₆] which appears to be the eleventh X-ray structure of an antimony porphyrin complex in the literature.

The molecular structures of the antimony(V) porphyrin cation [Sb(tpp)Cl₂]⁺ and the hexachloridoantimonate(V) [SbCl₆]^- anion of the title compound are given in Figure 1. The Sb atom of the porphyrin complex lies on an inversion center and at the same time in the porphyrin mean plane (C₂₄N₄). The average Sb—N distance and the Sb—Cl distance values, respectively equal to 2.062 (4) Å and 2.355 (1) Å, agree very well with those reported in literature (Liu et al., 1996; Tsunami et al., 2008). The Sb atom of the counter-anion is located on an inversion center and has a rhombic distorted octahedral environment with three values of Sb—Cl bond lengths [2.311 (3), 2.374 (2) and 2.393 (4) Å]. Such bond distances are comparable to those observed for similar porphyrin complexes (Soury et al., 2012). The cohesion of the structure is ensured by C—H··· Cl hydrogen bond interactions (Table 1). The crystal packing of compound [Sb(tpp)Cl₂][SbCl₆] is presented in Figure 2.

Experimental top

The title compound [Sb(tpp)Cl₂][SbCl₆] synthesis was performed under argon atmosphere. SbCl₅ (3–4 cm³) was added to a solution of tetraphenylporphyrin (H₂tpp) (500 mg, 0.814 mmol) in pyridine (25 cm³) and the resulting mixture was refluxed for 1 h. After removing pyridine and excess antimony pentachloride by rotary evaporation, the purple solid obtained was dissolved in dichloromethane and chromatographed on silica gel 60 (100 g, neutral, activity I). The reaction mixture was firstly eluted with CH₂C1₂ to eliminate any free H₂tpp present and then the title compound was eluted as a purple band using CH₂C1₂-methanol (2%). Single red crystals of the title complex, suitable for X-ray diffraction, have been obtained by diffusion of hexanes in dichloromethane solution.

Special details top

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