K 4 W(CN) 8 · 2 H 2 O was prepared by the reduction of WO 4 2−(in potassium cyanide medium) by KBH 4 . The reduction proceeds on the slow, drop‐by‐drop addition of concentrated acetic acid. The synthesis is simple and efficient because the reduction and complexation are accomplished at the same time.
