The earth‐metal olefin complex [Ga I (COD) 2 ] + [Al(OR F ) 4 ] − (COD=1,5‐cyclooctadiene; R F =C(CF 3 ) 3 ) constitutes the first homoleptic olefin complex of any main‐group metal accessible as a bulk compound. It is straight forward to prepare in good yield and constitutes an olefin complex of a main‐group metal that—similar to many transition‐metals—may adopt the +1 and +3 oxidation states opening potential applications. Crystallographic‐, vibrational‐ and computational investigations give an insight to the atypical bonding between an olefin and a main‐group metal. They are compared to classical transition‐metal relatives.
