Figure 2
A view of the packing along [1 3 1]₁₇ ∥ − a_bas, i.e. along the axis of the ribbons shown in Fig. 1

. Traces of important planes, all of which include the view direction, are marked; they are labeled both for the approximate commensurate supercell having Z′ = 17 and for the basic cell of the incommensurate description. Also marked are the short S⋯S contacts. The projections of axes b_bas and c_bas appear as dashed lines. The filled parallelograms isolate the areas of the inter-ribbon contacts that are probably most important in determining the modulation. The angles between [1 3 1]₁₇ ∥ − a_bas and [12 2 $[\overline 5]$ ]₁₇ ∥ − c*_bas is 81.3°; the angle with [10 $[\overline 4]$ $[\overline 7]$ ]₁₇ ∥ [2 0 $[\overline 1]$ ]_bas is 126.1°.
