Anomalous structure–luminescence relationship in phosphorescent gold(i) isonitrile neutral complexes
Abstract
A new compound that exhibits the shortest intermolecular Au⋯Au distance ever reported for neutral RNCAuX complexes is found to exhibit a counterintuitive higher-energy Au-centered phosphorescence than that in an analogous compound with a much longer Au⋯Au distance, presumably due to a different extent of excited-state distortion in dimers vs. extended chains.
