• techniques is that they produce deposits with relatively low metal contents as compared to CVD and ALD. Indeed, creating deposits with high metal contents is one of the biggest challenges for FIBID and FEBID, and recent advances in precursor design and fine-tuning of deposition parameters led to deposits of

• ), dissociative ionization (DI), neutral dissociation (ND), and dipolar dissociation (DD) [44][45][46][47][48][49][50][51][52]. One of the most important factors that govern deposit purity is the identity of ligands present in the precursor. The coordination sphere of ligands is addressed by precursor design [5

• structures in applications such as nanoprobes and sensors [4][5][6], or for the fabrication of superconductors [7][8][9][10] and plasmonic devices [11][12][13]. A lower carbon content can be achieved by means of precursor design [14], variation of deposition conditions [15], or post-deposition purification

The objective of this work is to expand the already existing library of gold(I) FEBID precursors and to study the effect of various substitutions at the core structure of a series of gold(I) N

The most elegant approach to precursor design yet is to use a bimetallic molecular structure to predefine
