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‘ = Bu^tNCH₂CH₂{C(NCSiMe₃ CHNBu^t)}; N‘ ‘ = N(SiMe₃)₂) and the anionic gallium(I) heterocycle [Ga(NArCH)₂][K(tmeda)] (Ar = 2,6-Prⁱ₂C₆H₃). The Nd−Ga bond energy is calculated to be 386 kJ mol^-1.
