Bis(ferrocenium) bis[tetrachloroantimonate(III)] trichloroantimony(III)

In the title compound, Fe(C₅H₅)₂]₂SbCl₄]₂SbCl₃], the cyclo­penta­dienyl rings in both cations are parallel, with a nearly eclipsed conformation. The Sb³⁺ ions are coordinated by six Cl^? ions to form octahedral arrangements, of which two are slightly distorted. These octahedra form infinite chains along the c axis through Cl—Sb—Cl bridges.
