[(C2H5)2NH2+]2(BSNDI2–) (4), and [(C2H5)3NH+]2(BSNDI2–) (5). The thermal stability, crystal structure, electron transport properties, and dielectric response were evaluated for these systems in terms of π-electron density and dimensional crossover from two-dimensional (2D) and one-dimensional (1D) to zero-dimensional (0D) electronic structures. Systematic modification of the counter cations from NH4+ to simple alkylammoniums
