Crystal structure of brackebuschite. The edge-sharing [MnO6] octahedra (green) form chains parallel to [010] with V1O4 and V2O4 tetrahedra (purple and violet, respectively) linked to them. These chains are held together by Pb1 and Pb2 (orange and yellow ellipsoids, respectively). Blue spheres of arbitrary radius represent H atoms. |
