A novel bis-dumbbell shape of a multi cation around a azaspirodecanium combined with nido-carborane was prepared in a single step in good yield starting from pyrrolidine and 1,3-dichloropropane to give one compound and from piperidine and 1,4-dichlorobutane to give the other. This is the first report of an electrolyte azaspirodecanium-boron-cluster structure. 1H,13C, and 11B nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, and high resolution mass spectrometry (HRMS) methods revealed changes due to interactions among the functional groups. In particular, the compound was electron-rich because of its unique structure and excellent chemical reactivity.
