The new ternary telluride TaPtTe{sub 5} has been prepared. It is a metallic, layered material whose structure has been determined by single-crystal x-ray diffraction methods. TaPtTe{sub 5} is isostructural with NbNiTe{sub 5} and TaNiTe{sub 5}. It crystallizes in space group D{sub 2h}{sup 17}-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) {angstrom}. The layers consist of bicapped trigonal prismatic Ta atoms and octahedral Pt atoms coordinated by Te atoms. TaPtTe{sub 5} displays good metallic conductivity along the a axis ({omega}{sub 298} = 9.7 {times} 10{sup 4} {Omega}{sup {minus}1} cm{sup {minus}1}) and is Pauliparamagnetic ({chi} = 2.1 {times} 10{sup {minus}4} emu mol{sup {minus}1}). The electrical and magnetic properties of TaPtTe{sub 5} are compared with those of NbNiTe{sub 5} and TaNiTe{sub 5}, as well as with the related compound NbPdTe{sub 5}. NbPdTe{sub 5} contains layers identical with those of the present series of compounds but stacked differently; it is a relatively poor metallic conductor.
