Magnesium−Magnesium Bond Stabilized by a Doubly Reduced α-Diimine: Synthesis and Structure of [K(THF)3]2[LMg−MgL] (L = [(2,6-iPr2C6H3)NC(Me)]22−)

A new Mg-Mg-bonded compound stabilized by a doubly reduced alpha-diimine ligand, [K(THF)(3)](2)[LMg-MgL] (L = [(2,6-(i)Pr(2)C(6)H(3))NC(Me)](2)(2-)), has been synthesized and characterized by single-crystal X-ray diffraction and density functional theory analysis. The Mg-Mg bond length is 2.9370(18) A.

New Pb–Pb bonds: syntheses and molecular structures of hexabiphenyldiplumbane and tri(trisbiphenylplumbyl)plumbate

Reaction of lead(II) chloride with biphenylmagnesium bromide yields Bp(3)Pb-PbBp(3) and [(THF)(3)Mg(mu-Cl)(3)Mg(THF)(3)][Pb(PbBp(3))(3)](Bp = biphenyl), which, upon single crystal X-ray crystallographic analysis, reveals an interesting variation of Pb-Pb bond distances.
