Di-chlorido-(5,10,15,20-tetra-phenyl-porphyrinato-κ(4) N)anti-mony(V) hexa-chlorido-anti-monate(V).

The asymmetric unit of the title compound, [Sb(C44H28N4)Cl2][SbCl6], consists of one half of an anti-mony(V) tetra-phenyl-porphyrin complex cation and one half of an hexa-chlorido-anti-monate(V) anion. In the complex cation, the Sb(V) atom lies on an inversion center and is octa-hedrally coordinated by four N atoms from a macrocyclic tetra-phenyl-porphyrinate 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](-) octa-hedron 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).
