Superconductivity in PdTe2 heavy transition metal based compounds is rapidly developing field in condensed matter physics community. Here, we report superconductivity in a nominal ternary telluride Ta2Pd0.97Te6 compound, which is synthesized in sealed evacuated quartz ampoule. The resultant compound is crystallized in layered monoclinic Ta4Pd3Te16 phase with space group C2/m, having lattice parameters a=21.304(6)A, b=3.7365(7)A, and c=17.7330A with Beta =120.65(1)degree. Both transport and magnetic measurements demonstrated bulk superconductivity at 4.4K in studied polycrystalline sample. The metallic normal state conductivity can be well ascribed to Fermi-liquid behaviour. The superconducting upper critical field of the compound is determined to be 5.5Tesla based on magneto-restively measurements.
