The synthesis of linear symmetric ethynyl‐ and acetylide‐ amidinates of the coinage metals is presented. Their photophysical properties were thoroughly investigated over a temperature range of 20—295 K. All compounds show azure, bright blue, or blue‐green microsecond‐long phosphorescence in the solid state. Short lifetimes and quantum yields of up to 41 % were determined. Furthermore, the complexes show pronounced PL in thf solution as well. The KIT logo on the cover represents photography of some of the substances under irradiation with UV‐light.
