The new ternary chalcogenide NbPdTe5 has been prepared by reaction among the elements at 700/750°C. NbPdTe5 crystallizes with four formula units in a cell with dimensions a = 15.673(9), Å, b = 3.728(2), Å, c = 12.720(6), Å in space group D162h-Pnma of the orthorhombic system. The structure has been refined to a final R index on F2o of 0.097 for 43 variables and 1786 observations. NbPdTe5 displays a new layered structural type. Each layer is composed of bicapped trigonal prismatic Nb atoms and octahedral Pd atoms coordinated by Te atoms. Electrical conductivity measurements show that NbPdTe5 is metallic; σ295 ≈ 1.3 × 103 Ω-1, cm-1. Although structurally NbPdTe5 is very similar to NbNiTe5, their electrical conductivity behavior is vastly different.
