We report on calorimetric, resistivity, and magnetization measurements on single crystal BaIrO3 and its derivatives. All results indicate a phase transition at Tc=175 K, and two additional features are observed in resistivity: a sharp peak at 80 K and an upturn at 26 K. It is found that dilute impurity doping with Sr drastically suppresses Tc and leads to an instant nonmetal to metal transition below Tc, underlining the instability of the ground state.
