Magnetic and calorimetric properties of Ba3TbRu2O9 are reported. Neutron diffraction measurements show that this compound adopts the 6H-perovskite structure with space group P63/mmc, in which the cation sites within the face-sharing octahedra are occupied by Ru ions and those within the corner-sharing octahedra are occupied by Tb ions. The magnetic susceptibility and specific heat measurements indicate that an antiferromagnetic transition occurred at 9.5 K. Neutron diffraction data collected at 2 K show that Ba3TbRu2O9 has a long-range antiferromagnetic ordering of Tb4+ ions. The moments of Tb4+ ions order ferromagnetically in the c planes, and these ferromagnetic planes are stacked antiferromagnetically along the c-axis. The direction of ordered moments is parallel to the c-axis. The ordered magnetic moment of Tb4+ ions is 6.84(4) μB.
