چکیده
In the title salt, C(11)H(21)N(2) (+)·C(6)H(5)O(3)S(-), which has two cation-anion pairs in the asymmetric unit, the two imidazolium cations are linked to two separate acceptor O atoms of one of the benzene-sulfonate anions through aromatic C-H⋯O hydrogen bonds, while the second anion is unassociated.

In this investigation, new structures based on homoisoflavonoids were designed. Homoisoflavonoids are considered as an important class of flavonoids with various biological properties such as cytotoxicity. A new series of benzylidene-6,7-dihydro-8H-[1,3]dioxolo[4,5-g] chromen-8-one derivatives were developed and their cytotoxic activities evaluated for all compounds on three human breast cancer...
متن کامل2-Hydroxymethyl-1,3-dimethylimidazolium iodide
The crystal packing of the title compound, C(6)H(11)N(2)O(+)·I(-), can be described as inter-calated layers lying parallel to (010), with the iodide ions located between the cations. A weak intra-molecular C-H⋯O hydrogen bond occurs within the cation. In the crystal, inter-molecular O-H⋯I hydrogen bonds result in the formation of a three-dimensional network and reinforce the cohesion of the ion...
