Synthesis, structural characterization, and theoretical studies of complexes of magnesium and calcium with gallium heterocycles

The examples of group 2 metal-gallium heterocycle complexes containing the first crystallographically characterized Ga-Mg and Ga-Ca bonds in molecular compounds are reported. These have the potential for use as a milder reagents for the transfer of the gallium heterocycles to less electropositive metals than the potassium salts of [:Ga{(ArNCH)2}(super -).
