Dicyanoaurates (DCAs) and tetracyanoplatinates (TCPs) have interesting properties that make them attractive for many applications. One such property is that these compounds contain tunable metal-metal (M∙∙∙M) bond distances. Gold and platinum compounds have been known to display a phenomenon called vapochromism due to changes in M∙∙∙M bond distances. Vapochromic materials exhibit changes in spectroscopic properties upon exposure to volatile organic compounds (VOCs). Utilizing DCAs and TCPs tunable M∙∙∙M bond distances could be beneficial in developing chemical sensors for detecting different VOCs in industrial and environmental settings. The synthesis and vapochromic behaviors of select DCA and TCP compounds with certain alkali, first row transition, and lanthanide metals will be presented.
