Abstract
The reaction of the copper(I) β-diketiminate copper complex {(Cu(BDI^{Mes}))_{2}(μ-C_{6}H_{6})} (BDI^{Mes} = N,N'-bis(2,4,6-trimethylphenyl)pentane-2,4-diiminate) with the low-valent group 13 metal β-diketiminates M(BDI^{Dip}) (M = Al or Ga; BDI^{Dip} = N,N'-bis(2,6-diisopropylphenyl)pentane-2,4-diiminate) in toluene afforded the complexes {(BDI^{Mes})CuAl(BDI^{Dip})} and {(BDI^{Mes})CuGa(BDI^{Dip})}. These feature unsupported copper-aluminum or copper-gallium bonds with short metal-metal distances, Cu-Al = 2.3010(6) Å and Cu-Ga = 2.2916(5) Å. Density functional theory (DFT) calculations showed that approximately half of the calculated association enthalpies can be attributed to London dispersion forces.
