Physical properties (magnetization, electrical resistivity and specific heat in the temperature range from 2 to 270 K (0.3-270 K for the resistivity)) have been determined for polycrystalline samples of the ternary compounds RPd(8)B(2 - x) (CePd(8)B(2 - x) type; space group C 2/c) and R(3)Pd(25 - x)B(8 - y) (La(3)Pd(25 - x)B(8 - y) type; space group P 2(1)/c) with R = La, Ce. Rietveld refinement of x-ray powder intensity data confirmed the crystal structure and single-phase condition. LaPd(8)B(2 - x) is a novel representative of the CePd(8)B(2 - x) type (a = 1.7838(1) nm, b = 1.040 24(4) nm, c = 1.164 60(6) nm, β = 118.56(1)°). Both cerium compounds behave like Kondo lattices.
多晶样品的物理性质（磁化率、电阻率和比热，温度范围为 2 到 270 K（电阻率为 0.3 到 270 K））已被确定为三元化合物 RPd(8)B(2 - x)（CePd(8)B(2 - x)型；空间群 C 2/c）和 R(3)Pd(25 - x)B(8 - y)（La(3)Pd(25 - x)B(8 - y)型；空间群 P 2(1)/c），其中 R = La，Ce。X 射线粉末强度数据的 Rietveld 精修证实了晶体结构和单相条件。LaPd(8)B(2 - x)是 CePd(8)B(2 - x)型的新型代表（a = 1.7838(1)nm，b = 1.04024(4)nm，c = 1.16460(6)nm，β = 118.56(1)°）。这两种铈化合物的行为都像 Kondo 晶格。
