Resumo

A range of new alkylpyridinium and imidazolium carborane salts with [nido-C2B9H12](-), [closo-CB11H12](-), and [RC2B11H11](-) (R = methyl or butyl) anions have been prepared and characterized by physical and thermal methods, including the solid state structures of five of the salts determined by single crystal X-ray diffraction. The tendency of the salts to form low-melting ionic liquids has been assessed; all the salts studied with [nido-C2B9H12](-) anions melted below 100 degrees C and, significantly, have melting points that are 25-85 degrees C lower than those of the corresponding [closo-CB11H12](-) analogs, demonstrating that a wider range of boron-rich ionic liquid materials can be readily accessed.
