Single crystals of five very low-melting ionic liquids, [emim]BF4 (mp −1.3 °C), [bmim]PF6 (+1.9 °C), [bmim]OTf (+6.7 °C), [hexpy]NTf2 (−3.6 °C), and [bmpyr]NTf2 (−10.8 °C), have been grown using a combined calorimetric and zone-melting approach and their crystal structures determined by X-ray diffraction.
