Single crystals of two new osmium-containing triple perovskites, Ba3LiOs2O9 and Ba3NaOs2O9, were grown from reactive molten hydroxide fluxes in sealed silver tubes. They crystallize in the space group P63/mmc with lattice parameters of a = 5.8025(1) Å, c = 14.1468(4) Å for Ba3LiOs2O9 and a = 5.8858(1) Å, c = 14.3451(5) Å for Ba3NaOs2O9. The magnetic susceptibility of these osmates indicates significant Os-Os coupling within the octahedra pair.
