Dichlorido(5,10,15,20-tetra­phenyl­porphyrinato-κ(4) 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 hexa­coordinated by four N atoms of the pyrrole rings of the tetra­phenyl­porphyrinate (TPP) ligands and two chloride ions, a half di-μ-chlorido-bis­[trichloridoanti­monate(III)] counter-anion and a dichloro­methane solvent mol­ecule. 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 inter­molecular C—H⋯Cl inter­actions involving the cations, the anions and the solvent mol­ecules. The solvent mol­ecule is disordered over two orientations in a 0.901 (13):0.099 (13) ratio.
