Dichlorido(5,10,15,20-tetra-phenyl-porphyrinato-?(4)N)anti-mony(V) hemi{di-?-chlorido-bis-[trichloridoanti-monate(III)]} dichloro-methane monosolvate.

ABSTRACT: The asymmetric unit of the title complex, [Sb(C(44)H(28)N(4))Cl(2)][Sb(2)Cl(8)](0.5)·CH(2)Cl(2), is composed of a Sb(V) complex cation wherein the Sb atom is hexa-coordinated by four N atoms of the pyrrole rings of the tetra-phenyl-porphyrinate (TPP) ligands and two chloride ions, a half di-?-chlorido-bis-[trichloridoanti-monate(III)] counter-anion and a dichloro-methane solvent mol-ecule. 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, SbN(4)C(20), 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 inter-molecular C-H?Cl inter-actions involving the cations, the anions and the solvent mol-ecules. The solvent mol-ecule is disordered over two orientations in a 0.901?(13):0.099?(13) ratio.
