Abstract
The asymmetric unit of the title complex, [Sb(C44H28N4)Cl-2][Sb2Cl8](0.5)center dot CH2Cl2, 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-mu-chlorido-bis[trichloridoantimonate(III)] counter-anion and a dichloromethane solvent molecule. In the cation, the average Sb-N distance is 2.066 (2) angstrom, while the Sb-Cl distances are 2.3410 (11) and 2.3639 (12) angstrom. 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) angstrom. 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) angstrom, the longest distances being between the Sb and bridging Cl atoms. The crystal structure is stabilized by intermolecular C-H center dot center dot center dot Cl inter actions 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.
