Platinocyanide
From Infogalactic: the planetary knowledge core
A platinocyanide is a salt containing the anion Pt(CN)42−. Barium platinocyanide, BaPt(CN)4, was important in the discovery of X-rays, and in the development of the fluoroscope. One platinocyanide salt with interesting conductive properties is Krogmann's salt, used in Cathode Ray Tube Televisions as the fluorescent material.
