The conventional approach to make mercury thiolate crystals is by a slow reaction of mercury salts with thiolates or disulfides to produce micrometer sized plate-like crystals of mercury thiolate. In this paper, the author discusses a new technique to produce such crystals - via sonication with neat thiols. The authors report that when a mixture of liquid mercury and an excess of neat 1-dodecanethiol was subjected to a medium-intensity ultrasound, rapid phase transition was observed, resulting in the formation of large crystals.As shown in Fig. 1, structures with a length of up to several hundred micrometers, a width of several tens of micrometers, and a thickness of about 100 nm were observed.
