The barium uranium sulfides Ba3.69US6, BaUS 3, and BaU2S5 have been synthesized at 1273, 1323, and 1323 K, respectively. The structures of these compounds have been determined by single-crystal X-ray diffraction methods. They crystallize in space groups D3d6-R3̄c, D2h16-Pnma, and C2h5-P21/c, respectively. Among these three ternaries and Ba2US6 the coordination geometries about the U atoms vary considerably. Ba 3.69US6 is a mixed U4+/U5+compound whereas the others are U4+ compounds. The decreasing dimensionality of the four compounds with increasing Ba-to-U content shows the expected trend.
