Halide perovskites play an important role in the history of gold chemistry. In fact, some of the earliest examples of halide perovskites contain gold. The mixed-valence Au(I)/Au(III) double perovskites have been studied since the 1920s. We have recently expanded gold perovskites to new architectures, which stabilize unexpected oxidation states. I will describe the physical and electronic structures and the properties of these new perovskites. I will also discuss how relativistic effects play a dominant role in the chemistry of gold perovskites, engendering unusual properties not seen in their lighter analogs.
