摘要：

The compounds EuMn2P2, EuMn2As2, EuMn2Sb2, YbMn2As2, and YbMn2Sb2 were prepared for the first time. Their crystal structure corresponds to that of Ce2O2S (ordered anti-"La2O3 or CaAl2Si2-type structure). Their lattice constants are reported. Attempts to prepare isotypic compounds with typically three-valent rare earth metals have failed so far. The new compounds can be rationalized as normal valence compounds with the expected oxidation numbers e.g. Eu2+Mn2+Mn2+P3-P3-. © 1979."
