A lanthanide-gallium complex stabilized by the N-heterocyclic carbene group
The complex [Nd(L'){Ga(NArCH)(2)}(N' ')(THF)], which exhibits the first f-element-gallium bond, is formed from the reaction between the N-heterocyclic carbene-supported neodymium complex [Nd(L')(N' ')(I)] (L' = (BuNCH2CH2)-N-t{C(NCSiMe3 CHNBut)}; N' ' = N(SiMe3)(2)) and the anionic gallium(I) heterocycle [Ga(NArCH)(2)][K(tmeda)] (Ar = 2,6-(Pr2C6H3)-C-i). The Nd-Ga bond energy is calculated to be 386 kJ mol(-1).
