Packing diagram for hexaaquanickel(II) bis(D-camphor-10-sulfonate) (CSD refcode LIJSOM; Henderson & Nicholson, 1995) viewed along [010], i.e. parallel to the triple layers. The green octahedra represent the nickel ion coordination shell viewed edge-on. Layers of cations parallel to (001) are held together by hydrogen bonds (highlighted with blue lines) between anions (acceptors) and cations (donors). No direct cation–cation hydrogen bonds are present. Adjacent layers are stacked one onto another without interdigitation. |
