Di­chlorido­(5,10,15,20-tetra­phenyl­porphyrinato-κ(4) N)anti­mony(V) hexa­chlorido­anti­monate(V)

The asymmetric unit of the title compound, [Sb(C(44)H(28)N(4))Cl(2)][SbCl(6)], 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 [SbCl(6)](−) 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).
