We have investigated the structural sequence of BaxC7 binary systems. X-ray diffraction measurements revealed that there exist at least four stable phase at x=3, 4, 6, and 9. Among them, structural models are presented for BajC70 and Ba3C70. Ba3C70 takes an analogous structure to AlS-BajC, but the unit cell is distorted to tetragonal with the cell doubling. BagCyg is fee, involves a distorted cube of Ba8 in the octahedral interstices. This x=9 structure is also known in K.9C10 as a saturated phase.
