Abstract
In most molecular crystals, crystal structure collapses when solvent molecules are removed. We report the crystal of (isobutylammonium+)(dibenzo[18]crown-6)[Ni(dmit)2]−•0.4CH3CN with Swiss cheese–like structure, in which 60% of the CH3CN sites are voids. The motion of isobutylammonium+ adjacent to the void sites maintains the single crystallinity, which occupy an apparently larger volume than in the static state. This study opens up the possibility of developing novel relaxor dielectrics based on molecular motion in the crystal of partially occupied voids.
