摘要：

The magnesium- and calcium-gallium heterocycle complexes [Mg-{Ga[(ArNCH)(2)]}(2)(THF)(3)] and [Ca{Ga[(ArNCR)(2)]}(2)(THF)(4)], R = H or Me, Ar = C6H3Pr2i-2,6, have been prepared via the reduction Of [I2Ga{ (ArNCR)(2)}] with the group 2 metal in tetrahydrofuran. The mechanisms of the reactions have been elucidated, and the crystal structures of the complexes exhibit the first structurally authenticated Ga-Mg and Ga-Ca bonds in molecular species, Theoretical studies suggest that the heterocycle-group 2 metal interactions have significant ionic character.
