Swap the coins! The Pt 2 Au 2 , Pt 2 Au 2 Cu 2 , and Pt 2 Au 2 Ag 2 complexes of 3,5‐dimethylpyrazolate exhibit yellow‐green, orange, and sky‐blue luminescence, respectively (see figure). The emission energies of Pt 2 Au 2 M 2 complexes can be controlled by the change of the third coinage metal ions M. The Pt 2 Au 2 M 2 complexes take the cis configuration with respect to the Au 2 M 2 plane.
