Abstract
We report synthesis and properties of superconducting BiPdPt, a new member of Bi-Pd based compounds known for their simultaneous existence of topological surfaces states and superconductivity. It crystallizes in a hexagonal structure having space group . A detailed investigation of the properties via transport, magnetization, and specific heat measurements confirm bulk superconductivity with transition temperature, \textit{T} = 4.0(1) K in moderate coupling limit.
