Imaging Physics, Lorentzweg 1, 2628CJ Delft, Netherlands 10.3762/bjnano.12.21 Abstract Seven gold(I) N-heterocyclic carbene (NHC) complexes were synthesized, characterized, and identified as suitable precursors for focused electron beam-induced deposition (FEBID). Several variations on the

The precursors that were synthesized had the general formula Au(NHC)X, and the effect of the variation of both the NHC ligand and the ancillary ligand X (X = Cl, Br, I, CF3) (Figure 1) was studied.

• ionic liquids decomposition of GaCp* is possible at temperatures below 300 °C with the aid of transition metals. Reactions of transition-metal complexes are reported to show H/D activation/exchange reactions at the C2 imidazolium carbon atom of the ionic liquid cation. The generated N-heterocyclic

• carbene ligands (NHC) stabilize metal clusters and nanoparticles [44]. By insertion of the transition-metal center into the C2–H bond of imidazolium salts, transition-metal hydride complexes are formed [45]. Finally, H transfer reactions from the transition metal to GaCp* lead to the release of Cp*H
