The title new compound Ce5AgBi3 was synthesized by arc melting method followed by annealing. The crystal structure refined using Rietveld method and X-ray powder diffraction data shows that it is similar to Hf5CuSn3 with space group p63/mcm (No.193). The unit cell parameters are a=b=9.7163(3)A, c=6.6228(2)A and V=541.47(5)A3. The structure is characterized by layers of Ce-Bi net formed by Ce and Bi at 6g position. Ce at 4f position and Ag at 2d position are separated in those two different kinds of Ce-Bi hexagon tunnels along c axes, respectively. Magnetism and specific heat property of Ce5AgBi3 are measured using PPMS. Ce5AgBi3 is antiferromagnetism and complies with Curie-Weiss law above TN=3.8K. The calculated moment is 2.67μB, fitted well with μeff of Ce3+，which means that the magnetism of Ce5AgBi3 is mainly offered by Ce3+.
