The new ternary chalcogenide NbPdTe/sub 5/ has been prepared by reaction among the elements at 700/750/degree/C. NbPdTe/sub 5/ crystallizes with four formula units in a cell with dimensions a = 15.673(9) /Angstrom/, b = 3.728(2) /Angstrom/, c = 12.720(6) /Angstrom/ in space group D/sub 2h//sup 16/-Pnma of the orthorhombic system. The structure has been refined to a final R index on F/sub 0//sup 2/ of 0.97 for 43 variables and 1786 observations. NbPdTe/sub 5/ 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 NbPdTe/sub 5/ is metallic; sigma/sub 295/ approx. 1.3 /times/ 10/sup 3/ ..cap omega../sup -1/ cm/sup -1/. Although structurally NbPdTe/sub 5/ is very similar to NbNiTe/sub 5/, their electrical conductivity behavior is vastly different.
