Abstract
The new ternary chalcogenide NbNiTe//5 has been prepared. NbNiTe//5 crystallizes with four formula units in a cell with dimensions a equals 3. 656(5), b equals 13. 075(16), c equals 15. 111(19) Angstrom in the orthorhombic system in space group D**1**7//2//h-Cmcm. The structure has been refined to a final R index on F**2//0 of 0. 037 for 25 variables and 1405 observations. NbNiTe//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//5 is a metal; its conductivity at room temperature is about 1. 3 multiplied by 10**4 OMEGA ** minus **1 cm** minus **1. Magnetic susceptibility measurements show that NbNiTe//5 is paramagnetic.
