Bistriflimide, also known variously as bis(trifluoromethane)sulfonimide, bis(trifluoromethanesulfonyl)imide, bis(trifluoromethanesulfonyl)imidate (and variations thereof), informally and somewhat inaccurately as triflimide or triflimidate, or by the abbreviations TFSI or NTf₂, is a non-coordinating anion with the chemical formula [(C F₃S O₂)₂N]⁻. Its salts are typically referred to as being metal triflimidates.
