  Superconductivity in low-dimensional compounds has long attracted much
interest. Here we report superconductivity in a low-dimensional ternary
telluride Ta4Pd3Te16 in which the repeating layers contain edge-sharing
octahedrally-coordinated PdTe2 chains along the crystallographic b axis.
Measurements of electrical resistivity, magnetic susceptibility and specific
heat on the Ta4Pd3Te16 crystals, grown via a self-flux method, consistently
demonstrate bulk superconductivity at 4.6 K. Further analyses of the data
indicate significant electron-electron interaction, which allows electronic
Cooper pairing in the present system.
