In all three structures, the phosphonium cation adopts a tetrahedral geometry at phosphorus, with C\u2014P\u2014C bond angles in the range 106.09\u2005(11)\u2013112.67\u2005(11)\u00b0. Hirshfeld surface analyses show that H...H and H...C contacts dominate the environments of the (4-bromobenzyl)triphenylphosphonium cations, whereas the perchlorate, tetrafluoroborate and triiodide anions are linked to the surrounding cations primarily through H...O, H...F and H...I contacts, respectively.\n
