Abstract

K4W(CN)8 · 2 H2O was prepared by the reduction of WO (in potassium cyanide medium) by KBH4. 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.
