The new layered ternary chalcogenide Nb8PtSe20 has been synthesized and structurally characterized. This compound crystallizes in the monoclinic system in space group C32hC2 m with cell dimensions a = 20.096(12), b = 3.433(2), c = 19.289(11), Å, and β = 107.1(5)°. This structure contains four unique Nb atoms, two in trigonal prismatic environments, one in a monocapped trigonal prismatic site, and one in a bicapped trigonal prism of Se atoms. The bicapped trigonal prism contains an SeSe bond (d = 2.36(2), Å). The Pt atoms exhibit square-planar coordination. Electrical conductivity measurements over the temperature range 110-300 K indicate that this material is a metal (σRT = 1.5 × 103 Ω-1, cm-1).
