We successfully synthesized silicon- and germanium-based allenes as isolable crystalline compounds. These allenes were found to have bent and fluxional structure in sharp contrast to carbon allenes having rigid linear structure. Remarkable red-shifts of the absorption bands of these allenes indicate the significant interactions between two cumulative double bonds.
