The preparation and structures of RE-mercury compounds The evaporating of mercury from amalgams

摘要

Compounds of Samarium, Gadolinium and Yttrium with mercury have been prepared by direct reaction between the RE-metals and mercury vapor at temperatures between 200 - 500℃. The RE-metals form compounds of the formulas ReHg, ReHg2 and ReHg3. The respective Sm compounds fit to the data, which have been given earlier. The Gd and Y compounds have prepared and studied for the first time. Their structures and lattice spacings have been evaluated and are very similar.
