Abstract

Crystals of Ba₅Ru_1.6W_0.4Cl₂O₉were prepared in a BaCl₂flux and investigated by X-ray diffraction methods. The structure of this new compound was solved and refined in the hexagonal symmetry space group P6₃/mmcwitha=5.817(2) Å,c=24.839(2) Å, andZ=2 to a finalRof 0.0383. The structure of Ba₅Ru_1.6W_0.4Cl₂O₉displays a 10-layer stacking sequence of mixed [BaO₃] and [BaCl] layers containing isolated (Ru/W)₂O₉units as face-shared octahedra. Isolated face-shared Ru₂O₉units are also found in Ba₅Ru₂Cl₂O₉which otherwise has a very different structure. Ba₅Ru_1.6W_0.4Cl₂O₉appears to be the first example of Ru and W sharing the same crystallographic site.
