摘要：

New ternary metal borides with composition R. E. T4B4 (R. E.=rare earth metal, T=transition metal) have been synthesized within the systems [La,Ce,Pr,Nd,Sm]-Os-B and [Y, La, Ce, Pr, Nd, Sm, Gd, Tb]-Ir-B. All compounds were found to be crystallizing with NdCo4B4-type structure. Magnetic measurements (80-300 K, Curie-Weiss behaviour, θp ~ 16K and μeff=9.94μB for TbIr4B4) indicate Y and R. E. elements (except Ce) to be trivalent in these compounds. The crystal chemistry of the isotypic series [Y, R. E.] [Os,Ir]4B4 is discussed. © 1979 Springer-Verlag.
