[1,4-Phenylenebis(methylene)]bis(triphenylphosphonium) bis(tetrafluoroborate)

Abstract

The crystal structure of the title salt, C44H38P2 2+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.
