Figure 5
Detail of the geometry of hydrogen bonds. A part of one Oc sheet and one Tet sheet of the consecutive (not of the same) layer is displayed in the projection along c*. Other sheets are removed. The basal triangles of tetrahedra are rotated `as close as possible' to OH2—OH3—OH3 triangles of unshared edges of M2 octahedra. Note: the Oc sheet is in the e position. |
