N2 - This study involved the synthesis of a novel compound, Pt1+xBi2, of which the structure was investigated using powder X-ray diffraction experiments and Rietveld analysis. These investigations confirmed a stuffed Cdl2-type structure (P3¯m1, D33d, No. 164), in which each Pt atom is coordinated by six Bi atoms to form a PtB16 octahedron, and these octahedra are connected by sharing edges to form a PtBi2 layer. The layers are stacked along the c-axis, and the excess Pt atoms partially occupy the interlayer formed by the octahedral interstices. Resistivity, magnetization, and specific heat measurements revealed the emergence of bulk superconductivity at 2.4 K in Ptj,2ôBi2-The triangular network of platinum and the structure composed of heavy elements that are expected to show strong spin-orbit coupling are anticipated to make this compound a useful platform for exploring exotic phenomena.
