Crystallization and structural characterization of dibenzo-18-crown-6·2(MeCN) and dibenzo-18-crown-6·2(MeNO2); assignment of specific C–H ⋯ O interactions
Abstract
Stoicheiometric 2 : 1 complexes of acetonitrile and nitromethane with dibenzo-18-crown-6 have been crystallized from the corresponding solvent and their structures established by single crystal X-ray diffraction techniques at –150 °C.
