Many microelectronic devices require thin films of silver or gold as wiring layers. We report silver(I) and gold(I) bicyclic amidinate complexes, wherein the constrained ligand geometry lessens the propensity for thermal decomposition. These new volatile compounds provide metallic films of silver and gold during CVD with hydrogen below 230 °C. [ABSTRACT FROM AUTHOR]
