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

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).

3,3'-Bis(chloro­meth­yl)-4,4'-dieth­oxy-1,1'-biphen­yl

The asymmetric unit of the title compound, C₁₈H₂₀Cl₂O₂, consists of a half-mol­ecule, the other half being generated by an inversion center, located at the mid-point of the benzene-benzene bond. Except for the two Cl atoms, all other atoms of the compound are nearly coplanar, with the atomic displacements from the mol­ecular mean plane ranging from 0.0037 (19) to 0.071 (2) Å. The two Cl atoms are in trans positions and are displaced with respect to the mean plane by 1.687 (2) and -1.693 (3) Å. The crystal packing is governed by van der Waals inter­actions.
