Abstract

Promethium polonide was prepared by reacting 147Pm metal with gaseous 210Po. The compound formed was assigned the 1:1 stoichiometry on the basis of calorimetric and X-ray analyses. The compound melted at 1292±25°C and possessed a Bl sodium chloride type structure with an a0 = 6·360±0·012Å and a calculated density of 9·61 g/cm3. The observed melting point and structural properties of PmPo agreed with the expected values based on the trends within the series of previously studied rare earth polonides.
