Abstract
The asymmetric unit of the title complex, [Sb(C44H28N4)Cl2][Sb2Cl8]0.5·CH2Cl2, is composed of a SbV 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, SbN4C20, 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.
