Crystal structure and physical properties of LaPd2Ge and a novel compound LaPdGe3.

Highlights: [•] A synthesizing of a new compound LaPdGe3 with the BaNiSn3 type crystal structure. [•] Refinement of the crystal structures of LaPd2Ge and LaPdGe3. [•] LaPd2Ge proved by heat capacity and thermopower to be as a new superconductor. [•] In opposite to LaPdSi3, the lack of superconductivity in its germanide analogue. [•] Large differences in the resistivity and thermopower between both studied germanides. [ABSTRACT FROM AUTHOR]
