  Phase equilibria in the palladium-rich part of the gallium–palladium system. The crystal structures of Ga3Pd7 and Ga1−xPd2+x

  摘要：

  The phase relations between the palladium-rich phases of the gallium-palladium system are clarified by combining preparative methodologies with powder X-ray diffraction and thermochemical analyses. A modified phase diagram of the palladium-rich part of the system is presented. The structure of Ga3Pd7, decomposing peritectoidally at 881(2)degreesC, was determined by powder X-ray diffraction and refined by a Rietveld profile fit. Ga3Pd7 adopts a new structure type with monoclinic space group symmetry: C2/m, Z = 2, a = 1359.46(2) pm, b=405.510(5) pm, c=544.339(6) pm, beta =105.2219(7)degrees, wR(p) = 0.082. The structure can be seen as a strongly distorted, ordered variant of a respective GaxPd1-x fcc solid solution. It comprises two structural motifs: layers of columns of fused (GaPd6/2)(2) prisms are formally separated by equiatomic GaPd layers. The impact of the composition on the structure of Co2Si-type Ga1-xPd2+x was studied. There exists a symmetry relation between the cubic close-packed arrangement of atoms and the structures of the Co2Si-type branch of AB(2) phases with Pearson symbol oP12 and space group symmetry Pnma.
