Stoichiometry-Driven Polymorphism of (Au3Pz3)2Ag Sandwich Clusters Enables Packing-Controlled Photoluminescence.
Controlling the photophysical properties of metal clusters without altering their intrinsic cores remains challenging because molecular structure and crystal packing are often strongly coupled in such system. Herein, we show that a cyclic trinuclear gold (I) complex (Au3) can serve as a structurally defined precursor f...
