Palladium(II) cyanides are chemical species with the empirical formula Pd(CN)n(2-n)−. The dicyanide (n = 2, CAS: [2035-66-7]) is a coordination polymer which was the first pure palladium compound isolated. In his attempts to produce pure platinum metal in 1804, W.H. Wollaston added mercuric cyanide to a solution of impure platinum metal in aqua regia to precipitate palladium cyanide which was then ignited to recover palladium metal - a new element.
