The variation of crystal system and conduction behavior of perovskite superconductor, BaPbo.75Bi0.2503-S, with oxygen deficiency was studied. The crystal system of BaPb,,,, BiO,,,O3. changed from orthorhombic through tetragonal to pseudo-cubic as 6 increases. The superconducting transition was obser
