(a) The supramolecular chain formed through intermolecular N—H⋯O and C—H⋯O interactions in (II), with dashed lines representing hydrogen bonds. [Symmetry code: (iv) −x + 2, y − , −z.] (b) Three-dimensional chains connected through C—H⋯O and C—H⋯π interactions involving the arene ring of the anion. [Symmetry code: (vi) x − 1, y − 1, z.] (c) A view of the π–π stacking interactions of salt (II) involving the aromatic ring of the anion and the imidazole ring of the creatinine cation. (d) A view of the extented helical chain along the b axis. |
