The title compound was prepared from the elemental components in a tantalum tube at 1070 K and investigated by X-ray diffraction of both powder as well as single crystals. The crystal structure was refined from four-circle diffractometer data: P21/n, a = 618.1(1), b = 613.6(1), c = 743.9(1) pm, β = 109.40(1)°, V = 0.2661(1) nm3, Z = 4, wR2 = 0.0536 for 1564 F2 values and 29 variables. EuPdGe crystallizes with the EuNiGe type structure. Both Pd and Ge atoms in EuPdGe have three germanium or
more » ... e germanium or palladium neighbors, respectively. They form two-dimensionally infinite [PdGe] polyanions which consist of corrugated 4.82 nets. These polyanions are separated by the europium atoms.
