摘要	A new platinum-based ternary selenide, Pt3Pb2Se2 was successfully synthesized at 1123 K by using a traditional solid-state method. It crystallizes in a orthorhombic structure with the Cmcm space group, and consists of quasi-2D [Pt3Pb2Se2] layers connected by inherent PtePb bonds. It is related to the parkerite structures with half transition metal occupation. Therefore, it belongs to the half anti-perovskite family structure. The R-T curve reveals its metallic behavior and shows high conductivity (RRR = 20.5) at room temperature. The X-ray photoelectron and ultraviolet photoelectron spectroscopy spectrums were collected. It has low work function (phi = -4.02 eV). First principles calculations were consistent with the experimental results. (c) 2020 Elsevier B.V. All rights reserved.
