Crystal engineering of aurophilic supramolecular architectures and coordination polymers based on butterfly-like copper–dicyanoaurate complexes: vapochromism, P–T behaviour and multi-metallic cocrystal formation

A family of bimetallic complexes based on aurophilic interactions was synthesized, and tested for vapochromism and P–T variations. These complexes can originate cocrystals, opening the route to a new aurophilic-based crystal engineering.
