Out of focus: A recent Communication published in this journal describes the synthesis of [nBu4N]HCO3. The authors performed a single-crystal X-ray study that revealed a putative species described as an incipient hydroxide ion engaging in a long, and presumably weak, interaction with CO2. Our recent exploration of the coordination chemistry of CO2 with small ions leads us to believe that such an exceptional bonding situation is unlikely. Instead, we argue that the crystal structure is that of [nBu4N]O2CCH3 and therefore not representative of the bulk powder from the synthesis.
