The new ternary chalcogenide NbNiTe/sub 5/ has been prepared. NbNiTe/sub 5/ crystallizes with four formula units in a cell with dimensions a = 3.656(5), b = 13.075(16), c = 15.111(10) A in the orthorhombic system in space group D/sub 2h//sup 17/-Cmcm. The structure has been refined to a final R index on F/sub o//sup 2/ of 0.037 for 25 variables and 1405 observations. NbNiTe/sub 5/ forms in a new layered structural type. Each layer consists of bicapped trigonal prismatic niobium atoms and octahedral nickel atoms coordinated by tellurium atoms. Electrical conductivity measurements indicate that NbNiTe/sub 5/ is a metal; its conductivity at room temperature is about 1.3 x 10/sup 4/ Omega/sup -1/ cm/sup -1/. Magnetic susceptibility measurements show that NbNiTe/sub 5/ is paramagnetic (X/sub rt/ approx. = 1.04 X 10/sup -3/ emu mole/sup -1/).
