The reactivity of gas phase lanthanide (Ln) atoms (Ln=La-Yb with the exception of Pm) with N2O from 298 to 623 K is reported. Lanthanide atoms were produced by the photodissociation of Ln(TMHD)3 (TMHD=2,2,6,6-tetramethyl-3,5-heptanat

The standard Gibbs energy changes for the formulation of an ionic or metallic monoxide from rare earth metal and sesquioxide have been calculated. Under high pressures ionic ytterbium monoxide and lighter rare earth metallic monoxides should be obtained, which is confirmed by experiments in a belt-type apparatus in the range 15-80 kbar and 500-1200 degree C. For Ln equals La, Ce, Pr, Nd, Sm, a face-centered cubic compound is obtained from each reaction. The cell parameters are respectively 5. 144, 5. 089, 5. 031, 4. 994, and 4. 943 plus or minus 0. 005 A. The compounds appear golden yellow with a metallic luster. From chemical analysis and cell parameter consideration it is concluded that these compounds are the rare earth monoxides. For Ln equals Gd, Dy, Tm, no reaction is observed at 50 kbar and 1000 degree C.
