The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate 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. ...[more]
