Crystal structure of the solid solution (Sr1.65Pb0.35)Al6O11
The title compound, di(strontium/lead) hexaaluminate, is a member of the solid solution series (Sr2-xPbx)Al6O11. It contains two statistically occupied M2+ (M = Sr, Pb) sites [both with site symmetries ..m; Sr:Pb occupancy ratios = 0.756 (2):0.244 (2) and 0.8968 (19):0.1032 (19)] that are located in...

| description | The title compound, di(strontium/lead) hexaaluminate, is a member of the solid solution series (Sr2-xPbx)Al6O11. It contains two statistically occupied M2+ (M = Sr, Pb) sites [both with site symmetries ..m; Sr:Pb occupancy ratios = 0.756 (2):0.244 (2) and 0.8968 (19):0.1032 (19)] that are located in the voids of an aluminate framework. The M2+ sites are surrounded by six and seven O atoms, respectively, if a cut-off M—O distance of 3 Å is chosen, resulting in considerably distorted MOx polyhedra. The aluminate framework consists of three AlO6 octahedra (two with point-group symmetries ..2/m and one with ..2) sharing edges to form partially filled layers extending parallel to (100) and located at x = 0, 0.5. Adjacent AlO6 layers are linked by a network made up from two crystallographically different AlO4 tetrahedra by sharing corners. |
