• ) may have a large influence on chemical stability and volatility. The crystal structure of the new precursor in FEBID, MeAuPMe3, is discussed in context with a larger group of gold complexes that either contain Au–CO or Au–PX3 bonds. In addition, the aurophilicity in a set of Au complexes is compared

• . Periodical DFT calculations of solid ClAuCO show that these Au–Au interactions destabilize the Au–CO bond in the crystal. The value of ΔG for the formation of AuCl is lowered to −1.8 kcal/mol, thereby explaining the short lifetime of solid ClAuCO in vacuum. The complexes ClAuPMe3 and ClAuPEt3 show medium and

• with optical extinctions in the near infrared (NIR). The Au@Co nanochains were synthesized via a one-pot galvanic replacement route involving a redox-transmetalation process in aqueous medium, where Au salt was reduced to form Au shells on Co seed templates, affording hollow Au@Co nanochains. The Au

• shells serve not only as a protective coating for the Co nanochain cores, but also to give rise to the optical properties of these unique nanostructures. Importantly, these bifunctional, magneto-optical Au@Co nanochains combine the advantages of nanophotonics (extinction at ca. 900 nm) and nanomagnetism
