Figure 2
The three-dimensional structure of (I). Displacement ellipsoids are drawn at the 50% probability level. For clarity, only one chain of Ca2+ cations connected via oxygen bridges is shown. From adjacent chains (above and below that shown), only O3 atoms are marked [symmetry code: (i) x, −y, + z]. Dashed lines show intralayer O—H⋯O hydrogen bonds. |
