Abstract
Sm(OH)2NO3, was prepared by hydrolysis of the corresponding nitrate, leading to a product which is insoluble in water. IR-spectroscopy showed a comparison with the analogous Gd-compound. The temperature of decomposition to SmONO3is below 573 K. The structure was refined by the Rietveld technique in space groupP21, (Z=2),a=6.3852(3) Å,b=3.7784(2) Å,c=7.7402(3) Å,β=97.572(3)°,V=185.11 Å3,Rp=4.9,Rwp=6.3,RB=4.0. The compound is isotypic with Ln(OH)2NO3(Ln=Pr,Nd,Gd). Infrared spectra and thermal decomposition data are also given for the Gd phase.
