## Abstract Seven new hexahelicenes (**3β7**, **9**, **10**) containing different functional group substituents have been synthesized and, in three cases (**4**, **8**, **10**), optically resolved. Optical rotations were measured and CD spectra are reported. Xβray crystal structures of the helicene
A solvate complex of (-)-1-menthoxygermatrane with chloroform (1) was obtained by reaction of (-)-menthoxytriethylstannane with 1 -bromogermatrane in chloroform. The crystal and molecular structure of 1 was established by X-ray analysis.
