Figure 4
Anisotropic displacement ellipsoid plot of 1 drawn at the 50% probability level of the edge-to-face π-system contacts that link the chains aligned along [001] in the [010] direction as well, thus offering an explanation for the observed two-dimensional sheets of anions. Hydrogen atoms except for those on carbon atoms C51 and C52 (and their symmetry equivalents) were omitted. The symmetry-equivalent mol­ecule was generated by a crystallographic inversion center with symmetry operator 1 − x, 2 − y, 1 − z.
