Description
The stacking polytype Ba6W4vacant2O18 is the first oxide variant of the Cs3Tl2Cl9-type. The structure determination gave for the space group R3c with the sequence (h)6, Z = 3, the refined, intensity related R' value of 6.8%. The octahedral net consists of groups of two face sharing WO6 octahedra (W2 Osub(6/2)O6), which are in the (110) plane displaced against each other. In the double octahedra the tungsten atoms are shifted away from their ideal central position (W-W:2.327 A) with the result, that the W-W distance has increased to 2.905 A. (author)
