The topology of the extended two-dimensional structures arising from (s)NH⋯O(s) interactions in modifications of sulfanilamide. Molecules are represented by their sulfonamide groups (arrows denote NH⋯O bonds and circles represent O atoms): (a) R22(8) dimers fused with R64(16) rings in form δ (see also Fig. 2a); (b) R22(8) dimers fused with R66(20) rings in forms α and γ; (c) fused R44(16) and R44(24) rings in form β. |
