| Strontium Ruthenocyanide, Sr2Ru(CN)6.15H2O, has been prepared by decomposing the insoluble lead salt with sulphuric acid and neutralising the filtered hydrogen ruthenocyanide with strontium hydroxide. It crystallises in pale straw-coloured, elongated plates, probably monoclinic, and which readily dissolve in water. The corresponding strontium ferrocyanide likewise crystallises with 15 molecules of water. |
