For the EuSn compound the magnetic properties have been investigated by de Vries et al. (1985). Magnetic ordering is found to occur at 10 K. In the paramagnetic range the dependence is in accordance with the Curie-Weiss law, the magnitude peSt indicates that europium is divalent.

R2M12P7. The unit-cell plot of R2M12P7 compounds (table 80 fig. 91) probably indicates a different valence state fi-om R " for cerium (in compounds with Fe, Co, Ni, Rh), europium (with Ni) and ytterbium (with Rh and Ni) atoms. The magnetic moment on the transition-metal atoms is observed only in cobalt compounds, magnetic properties of all other R2M12P7 compounds are caused by rare-earth atoms.
