Dichlorido(5,10,15,20-tetra­phenyl­porphyrinato-κ4 N)anti­mony(V) hemi{di-μ-chlorido-bis­[trichloridoanti­monate(III)]} dichloro­methane monosolvate

The asymmetric unit of the title complex, [Sb(C(44)H(28)N(4))Cl(2)][Sb(2)Cl(8)](0.5)·CH(2)Cl(2), is composed of a Sb(V) complex cation wherein the Sb atom is hexa-coordinated by four N atoms of the pyrrole rings of the tetra-phenyl-porphyrinate (TPP) ligands and two chloride ions, a half di-μ-chlorido-bis-[trichloridoanti-monate(III)] counter-anion and a dichloro-methane solvent mol-ecule. In the cation, the average Sb-N distance is 2.066 (2) Å, while the Sb-Cl distances are 2.3410 (11) and 2.3639 (12) Å. The central unit of the cation, SbN(4)C(20), is far from being planar, with deviations of atoms from the least-squares plane ranging from -0.110 (4) to 0.124 (4) Å. The Sb-Cl distances in the anion, which is located about an inversion center, lie in the wide range 2.3715 (13)-2.7489 (13) Å, the longest distances being between the Sb and bridging Cl atoms. The crystal structure is stabilized by inter-molecular C-H⋯Cl inter-actions involving the cations, the anions and the solvent mol-ecules. The solvent mol-ecule is disordered over two orientations in a 0.901 (13):0.099 (13) ratio.
