Abstract: The crystal structure of the title salt, C₄₄H₃₈P₂²⁺2BF₄^-, consists of discrete dications interlaced with the BF₄^- counter-ions. In each cation, both phosphonium groups lie on the same side of the plane of the central benzene ring. The tetrafluoroborate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.329 (6) to 1.391 (6) Å] deviate significantly from their standard values.
