Figure 5
Schematic representation of the (top) MDO1 and (bottom) MDO2 polytypes of NH4[Fe(thsa)2]. [Fe(thsa)2]− ions are represented by pairs of triangles which are blue on one side and red on the other side. Darker colours indicate a translation by a/2. The geometrical elements of partial sym­metry operations of layers and those relating adjacent layers are represented by the usual graphical symbols for symmetry elements. Screw axes and glide planes with nonstandard intrinsic translations are represented using the symbols for the 21 and n symmetry elements. Symbols of operations that are valid for the whole polytype are shown in red.
