Abstract

The new ternary telluride TaPtTe₅ has been prepared. It is a metallic, layered material whose structure has been determined by single-crystal X-ray diffraction methods. TaPtTe₅ is isostructural with NbNiTe₅ and TaNiTe₅. It crystallizes in space group D¹⁷_2h-Cmcm of the orthorhombic system with four formula units in a cell of dimensions a = 3.729(4), b = 13.231(11), c = 15.452(10) Å. The layers consist of bicapped trigonal prismatic Ta atoms and octahedral Pt atoms coordinated by Te atoms. TaPtTe₅ displays good metallic conductivity along the a axis (σ₂₉₈ = 9.7 × 10⁴ Ω^-1cm^-1) and is Pauli-paramagnetic (χ = 2.1 × 10^-4 emu mol^-1). The electrical and magnetic properties of TaPtTe₅ are compared with those of NbNiTe₅ and TaNiTe₅, as well as with the related compound NbPdTe₅. NbPdTe₅ contains layers identical with those of the present series of compounds but stacked differently; it is a relatively poor metallic conductor.
