The chemistry of the group 2 metals (beryllium, magnesium, calcium, strontium and barium) is dominated by the +2 oxidation state. Here we report the reductions of two magnesium(II) iodide complexes with potassium metal in toluene, leading to thermally stable magnesium(I) compounds, [(L)MgMg(L)] (L = [(Ar)NC(NPri2)N(Ar)]- or [{(Ar)NC(Me)}2CH]-; Ar = 2,6-diisopropylphenyl, Pri = isopropyl) in moderate yields. The results of X-ray crystallographic and theoretical studies are consistent with central Mg22+ units that have single, covalent magnesium-magnesium bonding interactions with 2.8508(12) and 2.8457(8) angstrom bond lengths respectively (where the number in parentheses indicates the standard deviation), and predominantly ionic interactions with the anionic ligands (L).
