%X A series of amidino-bridged mixed-metal
aluminum−magnesium complexes,
{[R2Al(μ-R‘2N)2Mg[(R‘‘)NC(R)N(R‘‘)]} (R = Me, R‘ =
i-Pr, R‘‘ = i-Pr, 1a; R
= Me, R‘ = i-Pr, R‘‘ = t-Bu, 1b;
R = Me, R‘ = i-Pr, R‘‘
= p-tolyl, 1c; R = Me, R‘ = Et, R‘‘ =
i-Pr, 2a; R = Me,
R‘ = Et, R‘‘ = t-Bu, 2b; R = Et, R‘ =
i-Pr, R‘‘ = i-Pr, 3a;
R = Et, R‘ = i-Pr, R‘‘ = t-Bu), were
prepared by insertion
reactions of the aluminum−magnesium complexes
[R2Al(μ-R‘2N)2Mg(μ-R)]n
(R = Me, Et; R‘ = Et, i-Pr) (n =
2,
4) with various substituted carbodiimides and characterized by mass spectra, IR spectra, elemental analysis,
and 1H and 13C NMR data. The structures of
two of
the compounds 1a,b have been determined by
single-crystal X-ray diffraction analysis. The structural
data
show that the bonding of the two nitrogens of the
carbodiimide to the magnesium atom is (σ, σ) symmetric
and indicate a weak interaction between Mg and C(15).
