A bit of a stretch! A series of stable Lewis base adducts of a dimeric magnesium(I) complex has been prepared and shown to possess exceptionally long Mg[BOND]Mg bonds. Theoretical studies on model compounds suggest the elongations of these bonds are low-energy processes. The structures of the magnesium(I) adducts are compared with those of related magnesium(II) hydride complexes (see picture; Mg pink, N blue, O red, H green).
