clusion compounds (see also the article by R. Bishop and I.G. Dance in volume
149 of this series).
The molecular sheets can remarkably also be linked by covalent bonds. An
alkane- or arenesulfonate anion (RSO 3 – ) 54 and the guanidinium cation 55 form
an interesting inorganic 2D net 56, in which the organic moieties Rs are sticking
out of the sheet (Fig. 14). The sheets are intercalatively layered in an R-dependent
manner (57 for the top view) [62]. A simple use of an alkane- or arenedisulfonate
58–62 (Fig. 14) results in covalent linkage of the neighbouring sheets
(63) [30].
