trifluoromethanesulfonic acid (HOTf) provides an efficient route to the known salt [In([18]crown-6)][OTf] in excellent yield. The analogous reaction employing trifluoroacetic acid (HTFA) allows for the isolation of [In([18]crown-6)][TFA], a monovalent indium complex for which the uncrowned salt is not stable at ambient conditions. The direct treatment of indium metal with HOTf, either in the presence or absence
